Abstract

The high efficiency, light weight, and reliability of hydrogen energy electrochemical equipment are among the future development directions. Membrane electrode assemblies (MEAs) and electrolyzers, as key components, have structures and strengths that determine the efficiency of their power generation and the hydrogen production efficiency of electrolyzers. This article summarizes the evolution of membrane electrode and electrolyzer structures, and their power and efficiency in recent years, highlighting the significant role of integrated structures in promoting proton transport and enhancing performance. Finally, it proposes the development direction of integrating electrolyte and electrode manufacturing using phase-change methods.
