Nonlinear modeling impedance electrochemical of PEM fuel cell

This article deals with modeling the impedance of a PEM fuel cell. This work is based on experimental measurements proven by the actual stack. The fuel cell model describes the phenomena by a complex impedance specific to each cell. This model is given in the form of mathematical equations describing the non-linearity of the model. The electrochemical impedance spectroscopy is requires studying the frequency behavior of the impedance model of the fuel cell by the Nyquist diagram. In this context, we have adopted the software “EIS Spectrum Analyzer”.
