Abstract
PtSn anode catalyst supported on carbon fiber was taken as the anode catalyst of the MEA. Commercial Pt/C as the cathode catalyst was used in MEA as the cathode catalyst. The Nafion 115 membrane was the proton exchange membrane of the MEA. MEA was fabricated by hot-pressing. The sing flat cell was assembled with the prepared MEA. The influences of temperature, ethanol concentration, rates of liquor and O2 were studied. The results showed that the performance of the fuel was better when the concentration of ethanol was 1.0 mol/L, the rate of liquor was 1.0 mL/min, the temperature was 80°C, and the rate of O2 was 100 mL/min, the maximum power density of the fuel reached about 18.2 mW/cm2.
