质子交换膜燃料电池催化剂的研究进展

Progress on Electrocatalysts for Proton exchange Membrane Fuel Cell

综述了近几年质子交换膜燃料电池中阳极催化剂和阴极催化剂的研究进展,对主要的阳极抗CO催化剂铂系合金催化剂的性能和机理进行了简介,其中Pt-Mo、Pt-WO3被认为是很有希望的抗CO的阳极催化剂。另外,多组分催化剂是比较有希望的研究方向。对阴极催化剂中的铂系合金、过渡金属、过渡金属复合氧化物、特别是钙钛石型氧化物等催化剂的性能和发展现状也作了简单评述。

The progress on anode and cathode electrocatalyst for PEMFC in the last few years are reviewed.The function and mechanism of major anode electrocatalyst are introduced in brief.Pt-Mo and Pt-WO 3 are good catalysts with CO tolerance.Multi component catalysts are expected to be more tolerant to CO.The performance and development of cathode catalyst are also explained.It involves platinum series、transition metal、oxides transition metal complexs、especially pyrochlore-type oxides et al.
