Anion-exchange membrane water electrolysis (AEM-WE) promises low cost, green hydrogen production for the future. In order to meet this potential, significant improvements to the performance and stability of catalyst layers (CLs) must be made, including the development of tailor-made ion conducting polymer materials. This Focus Review outlines the role of anion-exchange ionomers (AEIs) in CLs for enabling catalyst activation, enhancing stability toward delamination, and improving ion conduction. Detrimental effects such as inhibition of the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) and oxidative instability of the ionomer are also discussed with key findings from recent AEM-WE literature. Opportunities for future ionomer development are discussed to guide such efforts.

阴离子交换膜水电解离聚物开发的机遇

阴离子交换膜水电解（AEM-WE）有望在未来实现低成本、绿色制氢。为了满足这一潜力，必须对催化剂层（CL）的性能和稳定性进行重大改进，包括开发定制的离子导电聚合物材料。本焦点综述概述了阴离子交换离聚物 (AEI) 在 CL 中的作用，可实现催化剂活化、增强分层稳定性和改善离子传导。还讨论了离聚物的析氢反应 (HER) 和析氧反应 (OER) 的抑制以及氧化不稳定性等有害影响，以及最近 AEM-WE 文献中的主要发现。讨论了未来离聚物开发的机会，以指导此类努力。
