摘　　要：综合考虑了质子交换膜燃料电池及其空气和氢气供给系统,根据系统的工作要求,设计了一种实用而有效的控制方法。系统通过对空气和氢气进气量的调节,保证燃料电池输出电压和氢氧两侧压力符合系统要求。仿真研究建立了PEMFC和空气/氢气进气系统的数学模型,研究了燃料电池系统输出电压、阴阳极压力以及空气进气系统中的氧气分压和氧气质量变化,结果证明控制系统具有较好的动态性能和抗扰性,满足控制要求。A practical and effective control method was designed according to the working requirements based on the integrated consideration of PEMFC and air / hydrogen supply system. By adjusting the supply mass of hydrogen and oxygen, the output voltage and the pressure of hydrogen and oxygen could be satisfied with the system demands. The models of PEMFC and air / hydrogen supply system were set up in simulation study. The output-voltage, pressure of cathode and anode, oxygen mass and pressure of air supply system were discussed. The results show that the control system has the best dynamic performance and interference rejection, and is satisfied with the control demands.
