Parameters Identification of the Complex Impedance Model of the PEM Fuel Cell using Matlab/Simulink

摘要

In this work, we present a new technical method for identifying the complex impedance model parameters of a Proton Exchange Membrane (PEM) Fuel Cell for on-board diagnosis in real time. The study of the PEM Fuel Cell modelling is important in order to understand the physical phenomena that occurring in this green renewable energy source. A diagnosis method is presented by analyzing the behavior of the complex impedance. For this, we present the identification method of the various complex impedance parameters; this identification is based on mathematical methods using the least squares method and the interpolation analysis method. The results are obtained using Matlab/Simulink tools and allow us to validate the electrical model of the complex impedance. These results validate a modelling method for a rapid and real-time diagnosis of the PEM Fuel Cell complex impedance.
