| 英文摘要 | potential-scan tests were conducted to evaluate the stability of a ptru/c electrocatalyst at anode potentials in a direct methanol fuel cell (dmfc). the results show that, under normal operating conditions, the anode potential in a dmfc is benign for the ptru/c electrocatalyst. but in the case of deep discharge or short circuit, the anode potential value may exceed 0.6v versus dhe, which is harmful to the ptru/c electrocatalyst. the dissolution of catalyst components results in an enhanced ohmic resistance and a lowered catalytic activity for methanol electro-oxidation.
