摘要：

Anion exchange membrane water electrolysis cells (AEMWE) can take dilute alkaline solution or pure water as electrolyte, use relatively cheap anion exchange membrane and high activity of non-precious metal catalyst, effectively reduce the water electrolytic energy consumption and greatly reduce the input cost. In this paper, the performance characteristics and development advantages of AEMWE are summarized, and the research progress of key components such as the catalyst, anion-exchange membranes and ionomers in AEMWE are analyzed in detail. It is concluded that the Ni-Fe-based catalyst is the most promising anode material. By designing new catalyst layer and making porous structure, the problem of catalyst dissolution can be solved, while the ionic conductivity, water diffusion coefficient and durability of the ionomer and anion exchange membrane can be effectively increased by raising the ion exchange capacity. Finally, the future development directions of AEMWE are proposed, which are material innovation and preparation optimization of membrane electrode components, using pure water as the electrolyte, improving the flexibility of the test system, and developing efficient, low-cost and stable AEMWE hydrogen production device. © 2023 Chemical Industry Press.
