摘要：

低温碱性膜直接氨燃料电池（AEMDAFC）是实现氨能高效利用的有效途径，开发和优化燃料电池膜电极制备工艺是发展高性能、高稳定性AEMDAFC的关键。本研究基于膜电极制备工艺开发，系统考察了催化剂活化策略、催化剂负载量和催化剂与离聚物的混合比例等工况对膜电极电化学性能的影响。采用CCS和CCM结合法（记为CCMS）的膜电极制备技术，解决了膜电极破损和催化剂剥落等问题。通过分析极化曲线和电池性能的差异，综合优化膜电极制备工艺，实现了低温碱性膜直接氨燃料电池性能的提升。本研究优化的膜电极制备工艺为解决低温氨燃料电池中膜电极界面失效问题提供了具有普适性的方案，对于推动氨能高效转化具有重要参考价值。

Low-temperature anion exchange membrane direct ammonia fuel cells (AEMDAFC) are vital for the efficient conversion of ammonia into energy. Central to their advancement is the optimization of membrane electrode assembly (MEA) fabrication to ensure high power density and stability. In this work, based on the development of MEA fabrication processes, the effects of catalyst activation strategies, catalyst loadings, and catalyst-to-ionomer mixing ratios on the electrochemical performance of the MEA were systematically investigated. To mitigate common issues such as membrane rupture and catalyst peeling, a hybrid CCMS (catalyst-coated substrate and membrane) approach was developed. Detailed analysis of polarization characteristics and cell output facilitated the comprehensive optimization of the fabrication protocol, ultimately leading to superior performance in AEMDAFC. The hybrid CCMS fabrication protocol developed in this study offers a universal solution to mitigate interfacial instability in MEAs, providing significant technical insights for the advancement of low-temperature ammonia fuel cells.
