摘要
简要介绍了聚合物膜燃料电池(PEMFC)的特点及其存在的主要技术问题。综述了PEMFC阴极非Pt催化剂的研究进展,重点讨论了过渡金属硫族化合物、过渡金属合金、过渡金属氮化物、过渡金属氧化物以及过渡金属大环化合物等非Pt催化剂对氧还原反应(ORR)的催化活性、化学或电化学稳定性以及耐甲醇能力等性能,提出了阴极非Pt催化剂存在的问题以及发展趋势。Ru基硫族化合物、Pd基合金和过渡金属大环化合物催化剂具有良好的性能,有望成为PEMFC阴极Pt基催化剂的替代材料。
The advantages and major technical problems of polymer electrolyte membrane fuel cells （PEMFC） are briefly introduced. The research progress of non-platinum cathode catalysts of PEMFC is reviewed. In particular, the catalytic activity for oxygen reduction reaction （ORR）, chemical or electrochemical stability and methanol-tolerant of the non-platinum catalysts （transition metal ehalcogenides, transition metal alloys, transition metal nitrides, transition metal oxides, transition metal macrocyclie complexes, etc. ） are focused upon. The existing problems and the development trends of the non-platinum catalysts are proposed. The ruthenium-based chalcogenides, palladium-based alloys and transition metal macrocyelic complexes catalysts displayed good performances and are expected to become the substitutes for the PEMFC cathode platinum-based catalysts.
