Impedance Spectrometer Modelling in Matlab/Simulink for Measuring the Complex Impedance of a Fuel Cell –EIS Method

Abstract

Abstract-On the track of achieving the best fuel cell technology for the future, electrochemical impedance spectroscopy (EIS) is known to be the best tool so far in the field of diagnostic and understanding the behaviour of fuel cell. EIS is defined by the concept of measuring complex impedance and has a proper procedure to execute the diagnosis; it is a very strong tool to be carried out for PEM fuel cell because it give a lot of information about it. EIS measurement is developed and been carried out using a lot of software and programs. The modelling of EIS after having the complex measurement results from the diagnosis is a customary thing to do. This paper presents a novel method of EIS modelling using Matlab/Simulink. The concept of how EIS modelling works inside Matlab/Simulink and how the model is validated by experiments done before is explained inside the paper.
