Abstract：

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.
