摘　　要：介绍了甲醇替代燃料,如乙醇、甲酸等的研究进展。研究发现,用甲酸作燃料要比甲醇具有很多优点,如甲酸无毒,不易燃,存储和运输安全方便,而且它对Nafion膜的透过率低,氧化性能好。它在氧化时不产生使催化剂中毒的中间产物CO。在众多研究过的甲醇替代燃料中,甲酸被认为最有可能代替甲醇的燃料。The studies on the methanol-alternative fuels for direct methanol fuel cells（DMFC） have received much attention due to the problems of the direct methanol fuel cells.In this paper,the recent progress in the methanol-alternative fuels,such as ethanol and formic acid,is introduced.Compared with methanol,formic acid as the fuel has many advantages.For example,formic acid is non-toxic and inflammable.Thus,its storage and transportation is safe.It has low penetration rate through the Nafion membrane and excellent oxidation performance.During oxidation,it does not produce the CO intermediate,which can poison the catalyst.Therefore,among the numerous methanol-alternative fuels studied,formic acid is most likely to replace methanol as the fuel in DMFC.
