Résumé

In recent years, the fault diagnosis in Proton Exchange Membrane Fuel cell (PEMFC) becomes challenging issues in order to increase performance of the Fuel cell electric vehicle (FCEV). In fact, the occurrence of faults on different operation conditions into the FC unavoidable thus, lead-up to malfunctions in the FCEV and consequently, reduces its detect faults based on operating condition in different points is one of the most tackle in this area. Therefore, the main purpose of this paper is to evaluate the fault's effect on stack PEM fuel cell on a based on diving cycle tests by using a proposed faults sensitive model.
