摘　　要：针对频繁变载易导致车用质子交换膜燃料电池(PEMFC)性能下降、寿命缩短等问题,利用MATLAB/Simulink软件建立燃料电池发动机模型,研究燃料电池在不同影响因素下电压的动态响应,并在新欧洲行驶循环(NEDC)汽车工况下进行仿真分析。当反应温度为80℃、阴阳极气体分压均为300 kPa且膜含水量饱和时,燃料电池电堆输出电压较高,动态响应性能较好。仿真结果表明,反应温度、气体压力、膜含水量、加载速度和加载幅值等因素,会对燃料电池的动态响应性能产生影响。Aiming at the problems of performance degrading and life shortening of proton exchange membrane fuel cell(PEMFC)for vehicles caused by frequent load change,the fuel cell engine model was established by using MATLAB/Simulink to study the dynamic response of fuel cell voltage with different influencing factors.The simulation analyses were carried out under New European Driving Cycle(NEDC)vehicle operating condition.When the reaction temperature was 80℃,the partial pressure of anode and cathode gas was both 300 kPa and the membrane water content was saturated,the fuel cell reactor output voltage was higher and the dynamic response performance was better.The simulation results showed that dynamic responsiveness of fuel cells could be affected by the reasons such as reaction temperature,gas pressure,water content in the membrane,loading speed and loading amplitude,etc.
