聚合物电解质燃料电池中电催化剂的耐久性一直是电动汽车和固定热电联产系统商业化的主要关键问题。尽管已经提出了各种缓解方法，并且燃料电池堆的耐久性已经大大提高，但是对于在汽车应用中的使用，需要进一步提高耐久性。本文综述了PEFC阴极和阳极电催化剂的降解现象，并对降解机理进行了讨论。
Durability of electrocatalysts in polymer electrolyte fuel cells has been a major critical issue for commercialization of electric vehicles and stationary cogeneration systems. Though various methods mitigation have been proposed and the durability of fuel cell stacks has been greatly improved, further improvement of durability is needed for use in automotive applications. Here degradation phenomena of electrocatalysts for the cathode and the anode in PEFCs are reviewed and the mechanisms for degradation are discussed.
