Résumé
To improve the performances and lifetime of Low Temperature Proton Exchange Membrane Fuel Cell (LT-PEMFC), a good monitoring is necessary to detect and recover faults. In this article an online diagnosis method able to detect the most frequently reported faults in LT-PEMFC, namely flooding, drying, starvation and poisoning is proposed. This method is based on the use of the Electrochemical Impedance
