Abstract

In order to solve the problem of “methanol crossing-over” in direct methanol fuel cell (DMFC), the smooth Pt electrode was modified with iron tetrasulfonate phthalocyanine (FeTSPc). It was found that the electrocatalytic activity of the FeTSPc modified Pt electrode (Pt-FeTSPc) for oxygen reduction is similar to the Pt electrode. However, the electrocatalytic activity of the Pt-FeTSPc electrode for methanol oxidation is lower than that of the Pt electrode about 30.9%, demonstrating that the Pt-FeTSPc electrode has the good methanol-tolerant ability.

Key words: direct methanol fuel cell, iron tetrasulfonate phthalocyanine, Pt electrode, oxygen reduction, methanol-tolerant
