Promotion Effect of Heteropoly Acids Modified Electrode to Methanol Electrochemical Oxidation

Abstract

Abstract: Improving the rate of anode reaction in direct methanol fuel cell(DMFC) is the key to increasing the output power of DMFC. In this article, two kinds of heteropolyacids were applied to modify the platinum electrode and their effect on the methanol electrochemical oxidation was studied. The results show that the PWA and SiWA modified platinum electrodes have a promoting effect to the methanol electrochemical oxidation compared with the non-modified platinum electrode.

Key words: Direct methanol fuel cell, Heteropolyacids, Methanol electrochemical oxidation
