摘　　要：总结了燃料电池极化曲线的半经验公式,利用某80kW质子交换膜燃料电池试验数据来拟合公式中的相关系数,同时利用Matlab/Simulink软件建立了质子交换膜燃料电池堆的仿真模型,为燃料电池发动机系统的仿真和分析提供了一个重要工具。通过此模型可以研究燃料电池电堆的运行参数如气体压力、温度、当量比等对电堆性能的影响,从而有助于研究整个燃料电池发动机系统的性能。Semi-empirical polarization curve equations of PEMFC were summarized. The relative coefficients in the equations were fitted according to the experimental data of 80 kW PEMFC. Subsequently, the model of PEMFC was built with Matlab/ Simulink software, which provided an important tool for the analysis and simulation of fuel cell engine system. Through the model, the influences of operating parameters like pressure, temperature and equivalent ratio on the performance of fuel cell stack can be researched, which facilitates the performance research of the whole fuel cell system.
