ABSTRACT
Hydrogen production by water electrolysis is one of the most promising technologies for achieving an efficient use of intermittent renewable energy and a decarbonized future. Among various electrolysis technologies, the emerging anion exchange membrane water electrolysis (AEMWE) shows the most potential to produce green hydrogen at a competitive price. In this chapter, we give a comprehensive introduction to AEMWE, focusing on the reaction mechanism of cathode and anode, as well as cathode and anode electrocatalysts with high activity and stability. The representative catalyst design for achieving catalyst stability in long-term electrolysis operation is also classified and summarized. In addition, various strategies toward the improvement of HER/OER stability are summarized, and potential effective guidelines for the design of efficient catalysts are suggested. Finally, the current status and challenges as well as some possible solutions of AEMWE are summarized. This chapter can provide systematic insights for the development of highly efficient and stable electrocatalysts and promote the research and development of AEMWE.
