Analysis of Voltage Losses in High Temperature Proton Exchange Membrane Fuel Cells with Properties of Membrane Materials and Fluent Software

Abstract:

The mass and charge transport significantly affect the performance of fuel cells. A numerical model of high temperature proton exchange membrane fuel cells is developed. Ohmic losses and activation losses of both anode and cathode are analyzed at different design and operating condition. The polarization curve predicted by the model is in a reasonable agreement with published experimental data. The results of the model indicate that increasing the phosphoric acid doping level or operating temperature is helpful to decrease ohmic losses. The operating temperature has negligible impact on activation losses. Increasing the operating pressure can decrease activation losses.
