摘　　要：质子交换膜燃料电池金属双极板力学性能好、成形能力强、易批量制造,在近年研发及工程应用中得到广泛关注。但金属双极板易腐蚀、老化衰减速度快,已成为制约其快速产业化的重要障碍。而双极板产品评价依赖的现有标准体系侧重于基本性能测试,金属双极板老化衰减测评方法尚未统一。因此本研究通过综合电化学分析方法、物理测量方法、微观形貌表征等手段,提出适用燃料电池金属双极板的老化衰减测评方法,对于支撑金属双极板耐久性能评价及涂层工艺开发具有重要的理论与实践意义。Metal bipolar plates for proton exchange membrane fuel cells boast excellent mechanical properties,robust formability,and facile manufacturing processes,thereby garnering significant interests in recent researches and practical applications.Nonetheless,these plates are susceptible to corrosion and aging degradation,posing a pivotal challenge to fast industrial-scale adoption.The existing standard system for the evaluation of bipolar plate products focuses on basic performance testing,while the aging degradation evaluation methods for metal bipolar plates have not been unified.Therefore,this study introduces a comprehensive methodology that synergistically combines electrochemical analysis techniques,physical measurement,and microstructural morphology characterization.This integrated approach is of great theoretical and practical significance for supporting the evaluation of durability performance and coating technological development of metal bipolar plates.
