Dynamic PEM fuel cell modeling for automotive applications

This paper presents a static and dynamic modeling of a proton exchange membrane fuel cell (PEMFC) for transportation applications. Electrochemical analysis is performed to get an equivalent circuit of the fuel cell, which can be used, in the simulation of the power generator (association of the fuel cell and its converter). Experimental polarization curves and electrochemical impedance spectroscopy (EIS) are used to identify model parameters and to validate simulation results. Finally, experimental response to a current step is compared to the proposed model.
