Abstract

This article describes methods to model the functions of a PEM fuel cell stack system. Fuel cells are electrochemical devices that convert chemical energy of inputs reactants into output electrical energy. The proton exchange membrane fuel cell (PEM FC) is considered one of the most promising candidates for next-generation energy sources due to its high power density, zero emissions, and low operating temperature. Modeling has gained enormous attention and interest in recent years. This paper briefly reviews the types of PEM FC models such as Empirical/semi-empirical, analytical and mechanistic models, zero to three-dimensional models, multiphase flow models including optimization methods in PEM fuel cell models. In particular, this study focuses on the simulation of a standard semi-empirical mathematical model for an air-cooled PEM FC, utilizing the Simscape Electrical toolbox in the Matlab Simulink environment. The processes by which this model simulates the behavior of an air-cooled PEM FC are described in detail, illustrating the dynamic interactions between key physical and electrochemical parameters. This paper highlights the importance of combining different parameter modeling strategies in PEM FC modeling in order to achieve accurate results and reduce experimental costs.
