直接甲醇燃料电池阴极催化剂的研究进展

直接甲醇燃料电池（DMFC）功率密度高，燃料甲醇易得、储存和携带方便，既可作为大型的动力电源，又可作为小型电子设备的电源，是目前燃料电池研究领域的一个热点。但由于甲醇渗透、贵金属的使用等问题，阴极催化剂还有很多方面需要改善。介绍了近年来直接甲醇燃料电池阴极催化剂的研究与进展，提出了存在的问题及可能的发展趋势。

Research progress of cathodic electrocatalysts for direct methanol fuel cells

Direct methanol fuel cell(DMFC) has many advantages,such as high power density,abundant sources for methanol,convenience in storage and transportation of methanol.It can be used not only as the power for electric vehicle in large scale but also as the power for small electrical equipments,so that it has attracted much attention.However,because there are a lot of problems that affect the catalytic activity of the cathode,such as the methanol crossover and the use of noble metal,cathode catalysts for DMFC need to be improved.The recent research and development on cathode catalysts for DMFC are introduced and the problem,the possible trend are proposed in this paper.
