为了解决直接甲醇燃料电池(DMFC)中“甲醇渗透”的问题, 用大环化合物四磺酸基酞菁铁(FeTSPc)对光滑铂(Pt)电极进行修饰, 发现FeTSPc修饰的Pt电极(Pt-FeTSPc)和Pt电极对氧还原的电催化活性相近, 而Pt-FeTSPc电极对甲醇氧化的电催化活性比Pt电极下降30.9%, 表明Pt-FeTSPc电极有较好的耐甲醇能力.

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
