Abstract:

Hydrogen production from proton exchange membrane water electrolysis (PEMWE) has the advantages of its adaptability to intermittence and fluctuation of renewable energy such as wind and solar energy, high energy conversion efficiency, start-up quickly, small volume, etc., It has attracted great attention as a technology for green hydrogen production. Membrane electrode assembly (MEA), a key parts of hydrogen production from water electrolysis, is of significant importance to the performance, efficiency and lifetime of water electrolysis. Furthermore, its cost contribution to the overall system increases significantly with the increase of production capacity. It is critical to develop MEA with high performance, low cost and high durability for the large scale production of low cost green hydrogen. In this paper,the research progress and achievements of some key materials and components for MEA of PEMWE, including proton exchange membrane, catalyst layer, porous transport layer etc., as well as manufacturing technology of MEA are reviewed. Some progress on how to improve performance of hydrogen generation from water electrolysis, how to reduce the cost of MEA, etc., are systematically analyzed from the aspect of MEA design and development. Finally, some future research directions are proposed.

Key words: hydrogen production by water electrolysis, membrane electrode assembly, proton exchange membrane, catalyst layer, porous transport layer
