As substantial progress has been made in improving the performance of anion exchange membrane fuel cells (AEMFCs) over the last decade, the durability of AEMFCs has become the most critical requirement to deploy competitive energy conversion systems. Because of different operating environments from proton exchange membrane fuel cells, several AEMFC-specific component degradations have been identified as the limiting factors influencing the AEMFC durability. In this article, AEMFC durability protocol, the current status of AEMFC durability, and performance degradation mechanisms are reported based on the discussion during the US Department of Energy (DOE) Anion Exchange Membrane Workshop at Dallas, Texas, May 2019. With additional recent progress, we provide our perspectives on current technical challenges and future action to develop long-lasting AEMFCs.

阴离子交换膜燃料电池的耐久性挑战

在过去十年中，随着在改善阴离子交换膜燃料电池（AEMFC）性能方面已取得实质性进展，AEMFC的耐用性已成为部署竞争性能量转换系统的最关键要求。由于质子交换膜燃料电池的运行环境不同，已确定几种AEMFC特定的组件降解是影响AEMFC耐久性的限制因素。在本文中，根据2019年5月在德克萨斯州达拉斯的美国能源部（DOE）阴离子交换膜研讨会上的讨论，报告了AEMFC耐久性协议，AEMFC耐久性的当前状态以及性能下降机制。最近还有其他进展，
