摘　　要：针对车用燃料电池发动机关键部件膜电极的劣化模式,提出了一种基于超级电容主动补偿的燃料电池堆膜电极单体电压平衡控制方法,采用在燃料电池堆每个膜电极单体中都加入独立的主动补偿控制电路和独立的超级电容单体储能的电路结构,分别设计了主动补偿控制电路和燃料电池管理控制电路,实现了对每个膜电极单体工作电压的实时精确控制。According to the degradation mode of the membrane electrode parts in the automotive fuel cells stack engine,a voltage balance control method for the membrane electrode monomer was proposed based on the super capacitor active compensation.Independent active compensation control and independent super capacitor energy storage circuit structure were used for each membrane electrode monomer of the fuel cells stack.Active compensation control circuit and fuel cells stack engine control circuit were designed,and real-time precise control for operating voltage of each membrane electrode monomer was implemented.
