摘　　要：为了研究质子交换膜燃料电池(PEMFC)发电系统的电气特性,建立了PEMFC与DC-DC联合模型。首先,综合利用最小二乘法与粒子群优化算法对燃料电池动态模型进行参数估计,得到了与实际设备运行状态相符的模型;然后,使用Simpower建模方法对DC-DC转换器进行建模;最后,将燃料电池模型与DC-DC转换器结合进行仿真。仿真结果表明:该模型不仅较好地模拟了燃料电池的运行状态,还能够对燃料电池的输出电压进行良好的降压转化,在面对电压变化的情况下仍然能够保证其稳定输出。A joint model was established with PEMFC and DC-DC for better research on the electrical characteristics of the PEMFC system.Primarily,the empirical parameters were solved by the least square method and particle swarm optimization.Then,the DC-DC converter was modeled using Simpower method.Finally,a simulation combining PEMFC with DC-DC converter was discussed.The simulation results show that the model not only simulates the running state of the fuel cell well,but also can make a good step-down conversion of the output voltage of the fuel cell,thus ensuring the stable output of the fuel cell in the face of voltage changes.
