“…The typical reactions that take place at each porous electrode are the following: Water enters the cathode, usually a composite of Ni and YSZ or a perovskite-like material, where it is split to produce H 2 and oxygen anions that move through the solid electrolyte to the anode (perovskite-based like lanthanum strontium cobalt ferrite) to produce molecular oxygen. Proton-conducting SOEs operate with the same working principle as PEMEs (eqs –) …”

“…Proton-conducting SOEs operate with the same working principle as PEMEs (eqs 1−3). 10 SOEs, with their high temperatures, have the advantages of more favorable thermodynamics and faster kinetics than AEs and PEMEs. 11 They need less electrical energy to split water, operate at high current densities, produce pure hydrogen, and have higher efficiency.…”

A constellation of technologies has been researched with an eye toward enabling a hydrogen economy. Within the research fields of hydrogen production, storage, and utilization in fuel cells, various classes of materials have been developed that target higher efficiencies and utility. This Review examines recent progress in these research fields from the years 2011–2021, exploring the most commonly occurring concepts and the materials directions important to each field. Particular attention has been given to catalyst materials that enable the green production of hydrogen from water, chemical and physical storage systems, and materials used in technical capacities within fuel cells. The quantification of publication and materials trends provides a picture of the current state of development within each node of the hydrogen economy.

“…Evolved hydrogen gas diffuses back to the cathode electrode surface, from where H 2 is collected; simultaneously, O 2 − ions are conducted through the solid dense electrolyte, made of ZrO 2 ‐doped Y 2 O 3 , to the anode side (made of Lanthanum strontium manganite, LSM) and oxidizes to pure water at the anode‐electrolyte interface. Overall, SOWE produces ultrahigh purity H 2 (99.999%), with high efficiency 18 . The main disadvantage of this technique is the requirement of high temperature that necessitates thermally and chemically stable materials for electrodes, electrolytes and other cell components.…”

Water electrolysis (WE) is an electrochemical process that splits water and forms hydrogen and oxygen, in presence of catalyst. This is a rapidly developing technology owing to its extreme importance in the generation of hydrogen. Membrane-based WE involves the use of anion exchange, proton exchange and bipolar membranes, among which the anion exchange membrane-based WE technology is in the most advanced stage, followed by the proton exchange membrane-based WE. While, the bipolar membrane-based WE is the most nascent technology. Among the different categories of membranes used, polymer-based membranes are the most acceptable ones. It is evident that the structure and properties of the polymers that constitute a membrane play the most important role in determining its applicability in WE application. Keeping this in mind, this review is dedicatedly focused on the different polymers that have been majorly used so far in fabrication of anion exchange, proton exchange, and bipolar membranes for WE, and exclusively analyzes the influence imparted by the structure and properties of the involved polymers on the final performance of the membranes.

“…However, intermediate‐ and high‐temperature electrolyzers operate best with constant load and cannot be turned on/off easily. This, in turn, is a drawback for their coupling with wind/solar electricity, which will account for a large share of renewable electricity in the future [4,5] …”

What is Next in Anion‐Exchange Membrane Water Electrolyzers? Bottlenecks, Benefits, and Future

As highlighted by the recent roadmaps from the European Union and the United States, water electrolysis is the most valuable high‐intensity technology for producing green hydrogen. Currently, two commercial low‐temperature water electrolyzer technologies exist: alkaline water electrolyzer (A‐WE) and proton‐exchange membrane water electrolyzer (PEM‐WE). However, both have major drawbacks. A‐WE shows low productivity and efficiency, while PEM‐WE uses a significant amount of critical raw materials. Lately, the use of anion‐exchange membrane water electrolyzers (AEM‐WE) has been proposed to overcome the limitations of the current commercial systems. AEM‐WE could become the cornerstone to achieve an intense, safe, and resilient green hydrogen production to fulfill the hydrogen targets to achieve the 2050 decarbonization goals. Here, the status of AEM‐WE development is discussed, with a focus on the most critical aspects for research and highlighting the potential routes for overcoming the remaining issues. The Review closes with the future perspective on the AEM‐WE research indicating the targets to be achieved.
