Focusing on the main challenges of the anion exchange membrane fuel cell technology

After a few years of intensive research, recent studies of Anion Exchange Membrane Fuel Cells (AEMFCs) finally show cell performance at the required levels for automotive applications. This achievement was mainly due to the successful development of anion exchange membranes (AEMs) with considerable high hydroxide conductivity (100 mS cm-1 and above). Based on these high performance membranes, AEMFCs with power densities and limiting current densities higher than 1 W cm-2 and 4 A cm-2 have been recently achieved, which only a couple of years ago seemed far from possible. In order to make the next breakthrough and bring the AEMFC technology to the next levels, the following challenges need to be addressed: (A) the need for Pt-free (and PGM-free) catalysts highly active towards hydrogen oxidation reaction in alkaline medium, (B) carbonation issues while working with ambient air feed, and (C) barriers in cell performance stability. The TEEM lab at Technion is focusing its activities on these (and other) topics, aiming to make a significant impact in the AEMFC research community. Latest achievements of the TEEM lab in these AEMFC challenging fronts will be presented and discussed during the talk.

Cationic polyelectrolytes possess cationic groups as either a pendent functionality or integral to the main chain. In recent years, the study of cationic polymers possessing hydroxide counter ions have gained prominence. However, organic-based polymer cations are prone to nucleophilic attack by hydroxide ions, destroying the anion-exchange capacity and hydroxide ion conductivity. Numerous cationic head groups are being explored with a view to increasing the stability of cationic polymers in highly basic media. Despite rapid advancements, cationic polymers stable in caustic solutions at elevated temperatures have proved elusive.

In this presentation, we report on poly(arylene-imidazoliums), which were synthesized by microwave polycondensation of dialdehyde with bisbenzil and quantitatively functionalized by alkylation. This cationic polyelectrolyte is sterically protected around the C2-position and possesses a t1/2 of >5000 h in 10 M KOHaq at 100 ˚C. Alkaline stability is rationalized through analyses of model compounds, single crystal x-ray diffraction, and density functional theory. The polyelectrolytes form tough, pliable, transparent, anionically conductive films.

This presentation will discuss the latest developments of polyethylene-based (e.g. low density polyethylene – LDPE) radiation-grafted anion-exchange membranes (RG-AEM) being targeted at application in alkaline membrane fuel cells (AMFC). Evidence will be presented of high anion conductivities, high fuel cell performances (when used in combination with ETFE-based anion-exchange ionomer powders), and promising alkali stabilities. The scheme below outlines the general synthesis the RG-AEMs that will be discussed.

The figures above show: (left) the H2/O2 AMFC performances at 80 °C (PtRu/C anodes along with the stated cathode electrocatalysts) of an RG-AEM made from 15 µm thick LDPE film and (right) the change in hydroxide anion conductivity of the same RG-AEM over a period of 500 h.

Anion exchange membranes (AEMs) for use in alkaline fuel cells (AFCs) generally suffer from a combination of shortcomings in conductivity, durability, dimensional stability, and chemical stability. In this program, we have explored a strategy to address three of these requirements simultaneously through control of morphological behavior. Morphological behavior, including form, orientation, and continuity, is expected to have significant effects on conductivity. We seek to create materials that have co-continuous morphologies combining charged, hydrophilic domains for charge transport, and rigid hydrophobic domains for mechanical reinforcement and dimensional stability. Using trimethylamine as a model cation, reaction-induced phase separation was used to create polymer films with co-continuous morphologies and tunable mechanical behavior. This process generates a crosslinked, microphase separated film in one step through the reaction of copolymer of cationic block and a norbornene-functionalized block is reacted with cyclooctene (CO) and dicyclopentadiene (DCPD) to create. The resulting films were found to have excellent conductivity and reasonable mechanical properties. Mechanical properties can be modified by adjusting the relative amounts of CO and DCPD, and by adjusting the molecular weight of the cation-containing block copolymer. Subsequent efforts to improve mechanical properties and chemical stability, as required for device lifetimes, will also be described.

With the transformation from fossil-based energy generation to renewables, electrolytic hydrogen will play a key role. One limiting factor to widespread adoption of electrolysis for hydrogen production and energy storage are the specific investment costs of PEM-based systems. However, membrane electrolysis under alkaline operation enables elimination of expensive components while keeping many operational advantages of PEM systems. Even though the research efforts on OH-conducting polymers and membranes have been increased significantly in recent years there is still no concept with commercial maturity.

This presentation wants to derive some generic design rules and performance indicators how to translate intrinsic membrane properties systematically into in-situ performance. This holistic approach can provide a guideline for both academics and industry to better synchronize materials development with system requirements and vice versa.

The utilization of renewable energy resources such as wind and solar energy is in urgent demand. Energy storage devices using all-vanadium redox flow batteries have merits of high safety, long cycle life and flexible system design.[1,2] Electrolytes and membranes play critical roles for overall performance such as cycling efficiencies, capacity retention over cycling.[3-5] Herein, through modifying the commercial vanadium catholyte by adding additives, and through using a crosslinked and methylated meta-PBI membrane (Fig. 1a),[5,6] we have improved largely the Coulombic, voltage and energy efficiencies, in comparison with a commercial Nafion membrane (Fig. 1b,c).[7]

MnO2 as effective OER catalyst for Alkaline Anion Exchange Membrane Electrolysers

Hydrogen is a promising fuel and energy storage solution,  due to its highly efficient conversion between H2 and electricity and good energy density in comparison to most batteries. However, 95 % of the hydrogen is generated from non-renewable sources and 5% from electrolysis due to high cost of these systems[1,2]. Around 50% of the cost of the electrolyser system comes from the precious metal catalyst used in proton exchange membrane system due to acidic environment[3,4]. However, if alkaline anion exchange membrane water electrolyser AAEMWE is used, non-precious metal can be used for catalyst, flow fields and bipolar plates, reducing the cost significantly. It is estimated that replacement of PEM electrolysers wth AAEM electrolysers offers a 43% reduction in cell stack [5]

Oxygen evolution reaction (OER) catalysts which is the slowest of the reaction in the electrolyser systems and thus require more attention. Higher performances can be achieved using high alkaline concentration feed but this in turn reduces the lifetime of the system due to degradation of AEM membrane/ionomers. Thus in order to reduce the degradation and improve the lifetime, low alkaline concentration should be used as feed solution for AEMWE i.e. deionised water. We have shown previously [4] that a current density of 100 mA cm-2 at 1.65V using NiCo2O4 for OER could be achieved at 60 °C [4]. The current research is focused on MnO2 as very effective OER catalyst in the alkaline anion exchange membrane electrolyser. The catalyst has been characterized using XRD and SEM. Using low cost LDPE based membranes radiation grafted AEM, a very promising performance electrolyser was obtained of 1.57 V at 100 mA cm-2 and  a current density of 1 A cm-2 at a potential of 1.78 V in 0.01 M NaOH at 60 °C (Figure 1).

Amphoteric Membranes with Bilayer Architecture for
Vanadium Redox Flow Batteries

Redox-flow batteries are electrochemical energy storage devices aimed at grid-scale applications, for instance for time-shifting storage. They comprise an electrochemical converter and an external tank to store the electrolytes containing redox-active species. The all-vanadium redox flow battery (VFB) uses vanadium-ions in different oxidation states as redox-active species in the two electrolytes, thus irreversible contamination of electrolytes by cross-mixing is avoided. Nevertheless, transfer of vanadium ions across the membrane is to be avoided to minimize faradaic losses. Moreover, dissimilar rates of crossover of the 4 vanadium species can lead to electrolyte imbalance and, thus, capacity fading of the battery.

Here, we present a bilayer membrane concept consisting of Nafion® 212 that is laminated with a thin layer of meta-polybenzimidazole (mPBI). In the sulfuric acid based electrolyte of the VFB, the benzimidazole units of the PBI are protonated, thus forming an anion exchange polymer. The resulting membrane therefore has amphoteric character. Amphoteric membranes have previously shown to have promising properties for VFBs [1], combining the advantages for cation exchange and anion exchange membranes. The net vanadium transfer in this type of ionomer membrane is much more balanced (Figure 1) compared to pure cation or anion exchange membranes and, as a result, the capacity fading can be significantly reduced. Depending on the current density, the net vanadium flux across the membrane can be completely suppressed.

The hydrated morphology of anion exchange membrane is a key aspect in determining the ion conductivity. Here we examine changes in the morphology of polystyrene-b-poly(ethylene-co-butylene)-b-polystyrene (SEBS) functionalized with alkyl-substituted quaternary ammonium groups. The effects of the degree of functionalization, percentage of styrene and butyl spacer in the functional side chain were studied with dissipative particle dynamics (DPD) simulations. As anticipated, the results morphology controlled by both the degree of hydration and degree of functionalization. Perfect lamella, imperfect lamella, and non-regular structures were all observed under the various conditions. Among the three types, the imperfect lamella was made up of slices or subdomains of perfect lamella. These lamellae formed in different directions and were interconnected by the transitional regions. The hydrophilic phase swelled with hydration at each degree of functionalization. Domains of exclusive water were formed at the highest water contents (l º nH2O/SO3H = 16 or 20). An analysis of the cluster of water beads showed that percolation of the water may occur when the hydration level reaches about (l = 12). Lowering the functionalization of quaternary ammonium groups may postpone the formation of large connected water domains. Systems with the lower percentage of styrene did not form perfect lamella, but rather imperfect lamella and micelles were found at high hydration levels. With a butyl linker between the backbone and functional group, a perfect lamella morphology was formed at intermediate hydration levels. No perfect lamellae were formed with the butyl grafted as a tail. The butyl spacer appeared to reduce the swelling of the polystyrene blocks probably due to its hydrophobicity.

Figure Coarse-grained model of quaternary ammonium SEBS showing distinct spacer/tail on the TMA+. The block-to-block ratio of the copolymer is 8:152:8 for 17% mol. (30% wt.) as the primary, while 8:288:8 for 10% mol. as the variant.

In recent years, advances in alkaline exchange membrane fuel cells (AEMFCs) with anion exchange membrane (AEM) solid polymer electrolytes have gained traction due to their distinct – and potentially game-changing – advantages over proton exchange membrane fuel cells.  However, AEMs and AEMFCs are at a significantly less mature stage in their developmental than proton exchange membrane fuel cells (PEMFCs), and have experienced limitations specifically in the area of stability, carbonation, and achievable current and power densities, exhibiting a sizable performance gap vs PEMFCs.  This talk will focus on several fundamental and engineering advances that have enabled the creation of AEMFCs that are able to achieve ca. 2 W∙cm-2 peak power and 100’s of hours of stable operation, bringing AEMFCs much closer to the incumbent PEMFC technology, and opening the way to overcome the cost and reliability barriers that have slowed the growth and large scale market implementation of AEMFCs.

The three largest challenges facing AEMFCs today are: 1) understanding and controlling the water distribution in operating AEMFCs.  Water dynamics in these cells will be a primary theme of this presentation; 2) mitigating the negative influence of carbonation from atmospheric CO2 when using air as the oxidant.  The carbonate/bicarbonate formation and self-purging mechanisms will be discussed; and 3) reducing the platinum group metal (PGM) loading in the catalyst layers.  Strategies that included both PGM-free and low PGM (~0.1 mg∙cm-2) catalyts will be explored.  The overarching goal of this talk is not only to show the audience the state-of-the-art is in the field, but to also talk them through the mentality of our group in solving these problems and to provide some guidance regarding the approaches that have shown the most promise to date.

Anion exchange ionomers play a significant role in alkaline anion exchange membrane fuel cells (AEMFCs). A recent report has demonstrated 2600 mW/cm2 peak power density of an AEMFC employing an ETFE-based ionomer and commercially available catalysts [1], which emphasizes the importance of ionomers in AEMFC performance. Quaternized polyaromatic ionomers are another promising candidates as these materials possess not only good hydroxide conductivity and mechanical properties but also excellent alkaline stability and processability. However, reported AMFC performance employing polyaromatic ionomers is relatively poor. Last year, we presented the possible causes for the poor AMFC performance including the undesirable phenyl group adsorption [2] and cation-hydroxide-water co-adsorption [3] on hydrogen oxidation reaction catalysts. This year, we will report several molecular design strategy to minimize the undesirable adsorptions using several aryl-ether-free polyaromatic ionomers to demonstrate the progressive improvement of the AMFC performance up to 1,500 mW/cm2 peak power density. In addition, some questions related with AMFC MEA employing polyaromatic ionomers will be discussed:

  • Why Pt-Ru catalyzed AMFC performs better than Pt catalyzed AMFCs?
  • Why high anode flow rate improves much of AMFC performance?
  • What is cost effectiveness using polyaromatic ionomer for low-PGM, non-PGM, and non-Pt anode catalysts?
  • Is electrode flooding significant issue with polyaromatic ionomer-bonded electrodes?

A variety of energy storage and conversion electrochemical devices, such as polymer electrolyte membrane fuel cells, redox flow batteries, and water electrolysis, rely on ion-conducting polymer electrolyte membranes to separate and transport ions between the anode and cathode.1-3  Among these membranes, anion exchange membranes (AEMs) continue to receive increased attention because of their advantages of fast liquid fuel oxidation reaction in alkaline media, efficient water management, and the ability to use non-precious metal electrocatalysts for oxygen reduction reaction.4-6  Additionally, AEM-based electrochemical devices (as opposed to the liquid alkaline system) prevent leakage of corrosive fuels and carbonate precipitation.5,7  However, the most significant challenges currently preventing the advancement of AEMs in clean energy conversion technology are their poor chemical and mechanical stabilities under strong alkaline environment and low anion conductivity.  It is generally recognized that the stability of both polymer backbone and cation functional group play a crucial role in device durability.

In first part of the presentation, a chemically stable and elastomeric triblock copolymer, polystyrene-b-poly(ethylene-co-butylene)-b-polystyrene (SEBS), was functionalized with various benzyl- and alkyl-substituted quaternary ammonium (QA) groups for anion exchange membrane (AEM) fuel cell applications.  Synthetic methods involving transition metal-catalyzed C–H borylation and Suzuki coupling were utilized to incorporate six different QA structures to the polystyrene units of SEBS.  Changes in AEM properties as a result of different QA moieties and chemical stability under alkaline conditions were investigated.  Anion exchange polymers bearing the trimethyl ammonium pendants, the smallest QA cation moiety, exhibited the most significant changes in water uptake and block copolymer domain spacing to offer best ion transport properties.  It was demonstrated that incorporating stable cation structures to a polymer backbone comprising solely of C–H and C–C bonds resulted in AEM materials with improved long-term alkaline stability.  After 4 weeks in 1M NaOH at 60 °C and 80 °C, all six SEBS-QA AEMs remained chemically stable.  Fuel cell tests using benzyltrimethylammonium-containing SEBS (SEBS-TMA) as an AEM demonstrated excellent performance, generating one of the best maximum power density and lowest ohmic resistance with low Pt catalyst loaded electrode reported thus far.  Both polymer backbone and cation functional group remained stable after 110 h lifetime test at 60 °C.

In second part of the presentation, high molecular weight, quaternary ammonium-tethered poly(biphenyl alkylene)s without alkaline labile C–O bonds were synthesized via acid-catalyzed polycondensation reactions for the first time. Ion-exchange capacity was conveniently controlled by adjusting the feed ratio of two ketone monomers in the polymerization. The resultant anion exchange membranes showed high hydroxide ion conductivity up to 120 mS/cm and excellent alkaline stability at 80 °C. This study provides a new synthetic strategy for the preparation of anion exchange membranes with robust fuel cell performance and excellent stability.
