Description
Summary:The gradual flooding of a single PEM fuel cell was produced and Electrochemical Impedance Spectroscoy (EIS) measurements were realized in order to follow changes of the fuel cell impedance parameters. These changes were followed by using two equivalent circuit models: one simple model of the Randles type accounting for cathode and anode interfaces and a more complex model based on distributed elements, more suitable for porous electrodes in order to include protonic resistance of the catalyst layers
