โœฆ Synopsis

In a direct methanol fuel cell (DMFC) with a Na"on 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 CH OH, CO and CO in the exhaust gas of the cathode, the amount of methanol crossover was determined. Also, the e!ect of the thickness of polymer electrolyte membrane and the concentration of methanol solution on the amount of methanol crossover were investigated.

## Abstract The effect of methanol crossover on the fuel utilization of a passive direct methanol fuel cell (DMFC) was reported. The results revealed that the Faradaic efficiency decreased from 46.9 to 17.4% when methanol concentration increased from 1.0 to 8.0โ€‰molโ€‰L^โ€“1^ at the lower current densit
