摘要
直接甲醇燃料电池(DMFC)是电动汽车最为可行的电源。综述了作为甲醇氧化催化剂的铂及铂的多元体系;钙钛矿型氧化物的研究现状。概述了催化氧化反应机理;催化剂表面结构和性质以及电极电势对催化活性的影响。目前的催化剂是不令人满意的。基础研究将有助于我们避免用纯经验的方法来寻求更为理想的催化剂。
Direct methanol fuel cell (DMFC) is the most promising power generator for electric powered vehicles (EV). Pt and Pt polynary systems, the pyrochlore-type oxide as the catalyst for methanol oxidation was reviewed. Electrocatalytic reaction mechanism was summaried; influence of surface structure and properties of catalyst and electrode potential on catalysis activity was discussed. Today's catalysts are regarded critically. Fundamental research is necessary to avoid a purely empirical approach for the search for the better catalyst.
