Fault Diagnosis and Identification of Proton Exchange Membrane Fuell Cell System Using Electrochmical Impedance Spectroscopy Classification
Résumé
This paper deals with fault diagnosis of a Proton Exchange Membrane Fuel Cell (PEMFC) using a supervised method of classification coupled with
Electrochemical Impedance Spectroscopy (EIS). The purpose is to be able to detect if the fuel cell is in abnormal operating conditions and also to isolate the fault. To reach this aim, a classification method is tested on three different stacks, from different electrical power levels. The obtained results exhibit good performances while allowing an acceptable calculation time which can be beneficial in a context of on-line diagnosis.
