直接甲醇燃料电池的研究现状及技术进展

Research Status and Technical Progress of Direct Methanol Fuel Cells

论述了直接甲醇燃料电池在各研究机构取得的最新进展。由于DMFC目前存在甲醇的电催化活性低和甲醇从阳极到阴极的渗透问题 ,从电催化剂及电解质膜等两个方面概述了DMFC目前对于关键技术的研究现状及进展情况 ,指出研究开发新型电催化剂和电解质膜可以提高DMFC的性能 。

Direct methanol fuel cell(DMFC) is an ideal power source for application including vehicles and portable power source for its advantages such as simple structure, small size, light weight, anhydrous electrolyte and high energy density. The recent progresses of DMFC in various research units were introduced. Since the problems of DMFC to be solved are low activity of the catalysts and methanol crossover from the anode to the cathode, the research status and progress on main techniques of DMFC, as electrocatalysts and membrane, were described. The performance of DMFC can be improved by developing new electrocatalysts and membrane. The development trends and applications of DMFC were suggested.
