Abstract:

Carbonsupported CoMCP,FeMCP,MnMCP,CuMCP,NiMCP as cathodic catalyst were prepared. And the performance of MeMCP electrocatalysts was investigated by linear sweep vol\|tammetry(LSV). The electrochemical measurements demonstrate that MeMCP catalysts have good catalytic activity. The initial potential of MnMCP is 0.513 V, which has better catalytic performance. However, the initial potential of NiMCP is 0.198 V, which is the lowest among the five central metal catalysts. DMFC test shows that CoMCP,FeMCP,CuMCP and NiMCP have good catalytic performance in the DMFC.

Key words: direct methanol fuel cell, MeMCP, catalytic oxygen reduction, linear sweep voltammetry(LSV)
