Fuel cell simulation: Steady-state and dynamic case

Proton exchange membrane fuel cell (PEMFC) is a key of solving recent energy issues such as increasing carbon monoxide emission and energy consumption; however, the system of PEMFC is complex and unclear. Thus, the proper method for understanding the PEMFC system is urgently required. The purposes of this study are that design reliable control based and lumped model for PEMFC system and utilize the designed model for systematic analysis of PEMFC stack and variety operating logic. The model was designed using MathWork^® Matlab/Simulink. The model for the PEMFC stack consists four sub models which are the cathode, the anode, the membrane hydration, and the voltage model. Each model is based on the proper fluid dynamic and the thermodynamic principal. The I-V curves at varying pressure and relative humidity, which are the results of this model, show the reliable results. The results of this study´ control based PEMFC modeling, represent that they are a key of systematic approach of PEMFC.
