摘　　要：分析了质子交换膜燃料电池(PEMFC)的机理模型,在此基础上运用MATLAB的Simulink仿真工具,建立了PEMFC发电系统带负载模型。通过仿真,分析了负载对PEMFC电堆的各项动态特性(燃料的流量、效率、输出电压等)的影响,以及DC/DC、负载端的电压响应。仿真结果中负载电压呈三相交流正弦波形,表明搭建的整个PEMFC发电系统是基本正确的,为实现PEMFC并网的实时分析和动态优化提供了理论依据和参考方法。The mechanism model of proton exchange membrane fuel cell （PEMFC） was analyzed, based on this, the simulation tool of Simulink in Matlab was adopted to establish a model of the PEMFC power generation system with simple load, Through the simulation, the effect of the parameters on the dynamic output performance （the fuel flow rate, efficiency and output voltage etc.） of the PEMFC stack connected with load and performance of output voltage of the DC/DC and load was analyzed. Simulation results showed a three-phase AC sine wave load voltage,which indicated that the whole PEMFC power generation system model is basically correct, and it provided a theoretical basis and reference method to realize the real-time analysis and dynamic optimization of PEMFC connected with grid.
