Fault Diagnosis and Identification of Proton Exchange Membrane Fuel Cell System Using Electrochemical 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 results exhibit good performances and an acceptable calculation time what can allow to make some on-line diagnosis.
