The paper presents electrochemical measurements carried out in a PEMFC with a view to determining the separate kinetics of the electrode reactions. For this purpose; the separate response of one electrode (anode or cathode) was magnified by dilution of the reacting gas; respectively hydrogen and oxygen; and comparison of the experimental data in the form of steady voltage-current variations and impedance spectra. Experiments were carried out at 60 °C and ambient pressure. Water management was thoroughly controlled so that the gases leaving the cell had the same relative humidity in all experiments of one series. Hydrogen oxidation; although rapid; corresponds to overpotentials up to 50 mV at high dilution rates and current densities. Assuming a Tafel-Volmer mechanism; the exchange current density of the anode reaction at the Pt surface is of the order of 1 mA cm-2. The two techniques employed led to Tafel slopes of oxygen reduction ranging from 120 to 150 mV/decade; with an exchange current density near 1 μA cm-2; in good agreement with published data. © Springer Science+Business Media B.V. 2006;
