摘　　要：为了提高直接甲醇燃料电池阳极催化活性,通过浸渍法制备了PMo12修饰Pt/C电极,并采用粉末微电极技术比较研究了PMo12修饰Pt/C电极在硫酸溶液中的电化学性质及其对甲醇氧化反应的电催化性能。结果表明,甲醇在PMo12修饰Pt/C电极上的氧化速度能够明显提高。In order to improve the electrocatalytic activity of the anode in the direct methanol fuel cell, PMo12 modified Pt/C electrode was successfully prepared by immersion. The elcctrochimical quality in the sulphuric acid solution and the electrocatalysis to the methol oxidation of PMo12 modified Pt/C electrode and unmodified Pt/C electrode were compared by the technique of power microelectrode. The results show that the rate of the methol oxidation on the PMo12 modified Pt/C electrode was largely increased.
