综述了国内外在燃料电池氧还原催化剂方面贵金属与各种金属及非金属复合的研究进展,力求原材料成本低并可获得大的比表面积以提供更多的活性位点使催化剂的活性和催化效率提高,同时增强催化剂的稳定性,改善催化剂的抗毒化能力和氧还原性能,最终实现可观的性价比。
The research progress of recombination of precious metals and various metals and nonmetals in fuel cell oxygen reduction catalysts at home and abroad is reviewed. The aim is to reduce the cost of raw materials and to obtain large specific surface area to provide more active sites for catalyst activity and catalytic efficiency Improve, at the same time enhance the stability of the catalyst, improve the catalyst anti-poison ability and oxygen reduction performance, and ultimately achieve considerable cost.
