摘要：

In a direct methanol fuel cell (DMFC) with a Nafion membrane, a methanol solution fed to the anode permeates to the cathode. This phenomenon causes the depolarization loss at the cathode and the DMFC performance grows worse. In this research, by continuously measuring the concentration of CH3 OH, CO and CO2 in the exhaust gas of the cathode, the amount of methanol crossover was determined. Also, the effect of the thickness of polymer electrolyte membrane and the concentration of methanol solution on the amount of methanol crossover were investigated.
