Modeling and Simulation of Proton Exchange Membrane Fuel Cell Based on Matlab/Simulink

本文简述了质子交换膜燃料电池的结构及工作原理,重点介绍了燃料电池电压与电流模型结构和建模原理,并在Matlab/Simulink平台上对所建燃料电池模型进行仿真。仿真分析结果反映出电池活化极化损耗、欧姆损耗以及浓度极化损耗随电流增大而改变的关系,最终以燃料电池极化曲线的形式显示出来,为燃料电池电动汽车建模与控制仿真奠定基础。

This paper briefly described the structure and working principle of the proton exchange membrane fuel cell,focusing on the fuel cell voltage and current model structure and modeling principle,and simulated the built fuel cell model on the Matlab/Simulink platform.The simulation analysis results reflected the relationship between battery activation polarization loss,ohmic loss and concentration polarization loss as the current increased,and finally displayed in the form of fuel cell polarization curve,laying a foundation for fuel cell electric vehicle modeling and control simulation basis.
