Interface Design and Software Development for PEM Fuel Cell Modeling Based on Matlab/Simulink Environment

This paper is dealing with the interface design and software development for proton exchange membrane (PEM) fuel cell modeling based on Matlab/Simulink environment. Three models used in the software, steady-state mode, dynamic model and thermodynamic model, are described first. These models are then implemented through the graphic user interface (GUI) programming by Simulink, and the simulation results are visualized. There are voltage overshoots/ undershoots appearing in the results, which is come from the combination of electrical dynamic model and thermodynamic model. For the interface design and software development, a GUI file(*.fig) is designed in Matlab interactively, a main program (*.m) is coded using Matlab language, and a Simulink model (*.mdl) is designed based on the fuel cell model in the work. The Matlab main program calls Matlab GUI file and Simulink diagram to complete the fuel cell simulation. The software are applied to PEM fuel cell and solid oxide fuel cell (SOFC) successfully.
