The frequency behavior of the electrochemical model fuel cell by impedance spectroscopy

This paper discusses the frequency behavior of the impedance model fuel cell using the spectroscopy method. We used the “EIS Spectrum Analyser” software to view the influence of the different electrochemical components in the frequency domain. The frequency behavior is deducted by the Bode diagram or by the Nyquist plot. In this work, I focused on the impedance spectrum found by the Nyquist diagram. The form of the different models used in this work is found based on the deducted results for a certain frequency range and other defined parameters.
