摘　　要：自呼吸式直接甲醇燃料电池(DMFC)是一种没有辅助设备的便携式电源。由于自呼吸式DMFC输出性能较差,且负载在突然变化时不能及时响应并满足负载瞬时功率需求,因此通常需要添加辅助电源在负载变化时进行充电或放电,即采用混合供电模式。主要是对聚合物锂电池和超级电容组成的两种不同混合电源系统进行研究,通过实验表明:超级电容的混合电源系统可以更快的响应负载的变化。Air-breathing direct methanol fuel cell（DMFC） is a portable power without auxiliary equipment.Because the output performance of the DMFC performance is poor,and when the load changes suddenly,it can not respond or meet the load instantaneous power demand,so it is often necessary to add auxiliary power supply when the load changes in charge or discharge,which is a hybrid-powered model.Two different hybrid-powered models were studied in this paper,which composed of polymer lithium battery and super-capacitor hybrid power system.The experiments show that： the super capacitor hybrid power system is able to get the faster response to load changes.
