This project aims to provide a clear understanding of the degradation mechanisms of transition metal (M) and nitrogen (N) co-doped carbon (M-N-C) catalysts in acidic media by utilising new model catalysts, standardised degradation tests, comprehensive catalyst characterisation, and machine learning tools to interrogate mechanistic hypotheses and link degradation mechanisms to specific catalyst characteristics. This project expects to generate new knowledge on rationally designing robust hydrogen fuel cell catalysts. This will provide significant benefits, such as new knowledge on catalyst degradation, new catalysts for energy conversion applications, and collaborations with the industry to accelerate Australia’s shift to renewable energy.

该项目旨在通过使用新型催化剂、标准化降解测试、综合催化剂表征和机器学习工具来询问机制假设并将降解机制与特定催化剂特性联系起来，从而清楚地了解过渡金属(M)和氮(N)共掺杂碳（M-N- c）催化剂在酸性介质中的降解机制。该项目有望为合理设计稳健的氢燃料电池催化剂提供新知识。这将带来巨大的好处，例如关于催化剂降解的新知识，能源转换应用的新催化剂，以及与行业合作加速澳大利亚向可再生能源的转变。
