Abstract

PEMFC (Proton Exchange Membrane Fuel Cell) is considered as an attractive option to produce electric power in manyapplications. A fundamental step of theoretical fuel cell open circuit potential is examined and compared with the measured data from 1.2KW PEMFC module. The hydrogen pressure and stack temperature are also measured during the operation of PEMFC module. It is found that the stack voltage and current data agree in general with the results calculated by chemical potential approach though they still have a discrepancy. It is analysed that the discrepancy is due to activation polarization, concentration overvoltage and ohmic overvoltage.
