Abstract

The effects of operating parameters such as cell temperature, cathode pressure, methanol solution concentration and flux and oxygen flux on a liquid-feed direct methanol fuel cell with low catalyst loading (anode loading of Pt-Ru:0.4 mg·cm-2; cathode loading of Pt:0.4mg·cm-2) were studied experimentally. The emphasis on the effect of these parameters on the mass transfer inside the cell was discussed. The results showed that increasing the methanol solution flux and concentration not only enhanced the mass transfer of methanol to catalyst layer, but also accelerated the methanol crossover from anode to cathode. Also, the dynamic response of cell voltage to current was investigated under constant operating condition. The dynamic change of methanol crossover process plays the key role in the dynamic response of the cell voltage.
