摘要：

An original modelling of PEM fuel cell impedance is developed in our laboratory. It is based on the 1D resolution in the frequency domain of the physical equations taken into account the main phenomena encountered in PEM fuel cell: electrochemical reactions, ionic transport, charge and mass transfer in cathode electrode and GDL. In the present work, the impedance model has been validated on experimental impedance measurements run on 16 cells stack (400 W maximum electrical output) where every cell impedances have been recorded simultaneously. Coupled with a dynamic physical model an accurate stack characterisation has been performed over a relative large current density range from 0.08 A/cm(2) to 0.6 A/cm(2).
