Abstract
This review provides a comprehensive overview of the current state-of-the-art in anion exchange membrane (AEM) water electrolysis stacks, bridging advances from both academic research and main supplier companies. On the one hand, academic studies address the key components and operating conditions of AEM stacks, including electrocatalysts for the hydrogen evolution reaction and oxygen evolution reaction, with particular emphasis on catalysts synthesis optimization, scalability, and the transition toward noble-metal-free alternatives. The selection and development of durable AEMs and porous transport layers, as well as parameters such as temperature, electrolyte composition, and concentration, are also examined as key factors that govern stack performance and stability. On the other hand, the principal AEM stacks that are commercially available were also reviewed to compare and evaluate industrial-scale AEM stack operation, thereby contextualizing academic advances within real-world performance.
期刊介绍:
Current Opinion in Chemical Engineering is devoted to bringing forth short and focused review articles written by experts on current advances in different areas of chemical engineering. Only invited review articles will be published.
The goals of each review article in Current Opinion in Chemical Engineering are:
1. To acquaint the reader/researcher with the most important recent papers in the given topic.
2. To provide the reader with the views/opinions of the expert in each topic.
The reviews are short (about 2500 words or 5-10 printed pages with figures) and serve as an invaluable source of information for researchers, teachers, professionals and students. The reviews also aim to stimulate exchange of ideas among experts.
Themed sections:
Each review will focus on particular aspects of one of the following themed sections of chemical engineering:
1. Nanotechnology
2. Energy and environmental engineering
3. Biotechnology and bioprocess engineering
4. Biological engineering (covering tissue engineering, regenerative medicine, drug delivery)
5. Separation engineering (covering membrane technologies, adsorbents, desalination, distillation etc.)
6. Materials engineering (covering biomaterials, inorganic especially ceramic materials, nanostructured materials).
7. Process systems engineering
8. Reaction engineering and catalysis.
