摘要：

碱性膜电解水制氢和燃料电池技术是氢能产业链上的重要产氢和用氢技术。作为碱性膜电解槽及燃料电池的核心部件，阴离子交换膜承担着传递氢氧根离子、阻隔气体渗透、分隔正负两极的重要作用，决定着电化学过程效率和性能。现有阴离子交换膜的氢氧根传导率偏低和耐碱稳定性不高的问题严重制约着产氢和氢能转化效率。本文综述了近年来面向碱性膜电解水制氢和燃料电池应用的阴离子交换膜的发展动态，特别是在强化离子传导率、提高耐碱稳定性方面的方法和进展，以及膜材料化学组成和结构对膜性能的影响。

Alkaline membrane water electrolysis and fuel cell technology are important hydrogen production and utilization technologies in the hydrogen energy industry chain. As the core component of alkaline membrane electrolyzer and fuel cell, the anion exchange membrane (AEM) plays an important role in transferring hydroxide ions, blocking gas permeation, and separating positive and negative electrodes, which determines the efficiency and performance of the electrochemical process. The low hydroxide conductivity and poor alkaline stability of existing AEM seriously limit the efficiency of hydrogen production and conversion. This paper reviews recent developments in AEM for alkaline membrane water electrolysis and fuel cell, in particular the methods and progress in enhancing ion conductivity and improving alkaline stability, and the influence of membrane material chemical composition and structure on membrane performance.
