摘 要: 评述了直接甲醇燃料电池阳极电催化剂研究中的几个热点问题 ,简述了催化剂材料的制备方法和最新的发展情况 ,概述了铂基二元、三元、四元催化剂材料的研究现状、取得的主要成果和存在的主要问题 ;铂基钙钛矿类和非铂基催化剂的成本低 ,但需要进一步解决在酸性介质中的寿命短和活性低的问题。 Some questions about electro catalysts for anodic methanol oxidation in the direct methanol fuel cell are discussed.In this paper,the methods for the preparation of catalysts,the problems and successes of binary,ternary and quatemary platinum alloy catalysts in the DMFCs have been reviewed.Although perovskite and non platinum anode catalysts are less cost,their electro catalysis activities in methanol oxidation and stabilities in acid medium have to be improved for further work.
