In the face of the imminent challenges of climate change, hydrogen holds the potential to replace fossil fuels as a green and sustainable energy resource. Anion-exchange membrane water electrolyzer (AEMWE) is a quickly rising technology for hydrogen production due to various advantages, including an inexpensive membrane, non-precious metal catalysts, compact size, easy integration with and adaptation to green power, etc. AEMWE involves a typical combination of electrocatalysts, an anion-exchange membrane, membrane electrode assembly, flow channel design, system integration, and green power fluctuation working condition adaptability. However, AEMWE suffers from unsatisfactory operational durability from both individual components and system integration levels, restricting its large-scale application. The development of highly durable AEMWE requires rational and systematic analysis and evaluation of each component for practical integration. This review discusses the durability-limiting factors and common strategies to improve stability based on each level of the AEMWE system, thus fostering future academic and industrial development of highly durable AEMWEs.

阴离子交换膜水电解槽从组件到集成层的稳定性挑战


面对气候变化的迫在眉睫的挑战，氢有可能取代化石燃料成为一种绿色和可持续的能源资源。阴离子交换膜水电解槽 （AEMWE） 是一种迅速崛起的制氢技术，具有膜价格低廉、非贵金属催化剂、体积小、易于集成和适应绿色能源等优点。AEMWE 涉及电催化剂、阴离子交换膜、膜电极组件、流道设计、系统集成和绿色电力波动工况适应性的典型组合。然而，AEMWE 在单个组件和系统集成水平方面的运行耐久性都不尽如人意，限制了其大规模应用。高耐久性 AEMWE 的开发需要对每个组件进行理性、系统的分析和评估，以便进行实际集成。本文讨论了基于 AEMWE 系统各个级别的耐久性限制因素和提高稳定性的常见策略，从而促进高耐久性 AEMWE 的未来学术和工业发展。
