Characterization of the Parameters of the Open Cathode Stack Fuel Cell using an Experimental Work

Abstract

This work deals the characterization of a PEM fuel cell by the impedance spectroscopy method. A test bench is set up to allow measurements by the method of impedance spectroscopy under different current values. An Open Cathode Stack Pragma Industries fuel cell system is composed from 20 cells. A fuel cell modeling is based on the electrical elements. We used the method of « least square » to determine the parameters of the model based on measured values. The model is simulated in Matlab/Simulink.
