中文摘要：

由烟碱的酰胺在 DMFC 的阳极上工作组成的一组液体催化剂在一个磅电极被调查，它是烟碱的酰胺，菸碱 adenimdinucleotide (NAD~+) 和它的 plwsphate (NAD (P )~+) 。在三个反应系统的甲醇阳极氧化的动力学被 measuringpotentiodynamic 比较当前潜力的曲线和 ACimpedances。试验性的结果显示出那，在 Ptelectrode 的甲醇氧化的动态 beliavior 与增加三种物质被改变了。这些辅酶和烟碱的酰胺的催化作用上的温度的影响被在不同温度比较甲醇氧化的 AC 阻抗系列讨论。

英文摘要：

A group of liquid catalysts composed of nicotinic amide functioning on the anode of DMFC were investigated at a Pt eleetrode, which were nicotinic amide, nicotinamide adenine dinucleotide （ NAD^＋ ） and its phosphate （ NAD （ P ） ^＋ ）. The kinetics of methanol anode oxidation in the three reaction systems was compared by measuring poteatiodynarnic current-potential curves and AC impedances. The experimeatal results show that the dynamic behavior of methanol oxidation at a Pt electrode has been changed with adding the three substances. The influence of temperature on the catalysis of these coenzymes and nicotinic amicle was discussed by comparing the AC impedances spectra of methanol oxidation at differeat temperatures.
