| Abstract: | Direct methanol fuel cell(DMFC) has attracted more and more attention due to its many advantages.However,DMFC has some main problems that prevent its practical application.One of the problems of DMFC is the low electrocatalytic activity of its cathodic Pt catalyst for the oxygen reduction.The present paper covers carbon-supported tetra-phenyl cobalt porphyrin(CoTPP) and Pt(CoTPP-Pt/C) catalysts prepared.The electrochemical measurements demonstrate that the electrocatalytic activity of CoTPP-Pt/C catalyst for the oxygen reduction is higher than that of carbon supported Pt(Pt/C) catalyst.The current density of the oxygen reduction at CoTPP-Pt/C catalyst is about 30% higher than that of Pt/C catalyst.However,the methanol resistant ability of the CoTPP-Pt/C catalyst is similar to that of Pt/C catalyst.Thus,it should be improved. |
