摘要： 面向空间应用，依据某航天器任务期间的功耗需求，采用燃料电池和蓄电池的架构，对1kW燃料电池电源系统的设计与实现进行研究。构建了1kW燃料电池电源系统仿真模型，对系统设计原理进行了仿真验证，并研制了1kW燃料电池电源系统样机，对系统典型的负载阶跃工况进行了试验测试。试验测试结果表明，1kW燃料电池电源系统在半载阶跃变化时，母线电压波动小于5V，调节时间小于25μs；整个运行过程系统工作正常稳定，能够满足航天器空间应用需求。

Abstract: Aiming at the space application and according to the demand of one spacecraft’s power consumption during a task, an architecture of a fuelcell and a storage battery was used to research the design and implementation of a 1kW fuelcell power system. A simulation model of the system used to verify the system’s design principle was built. Also, a prototype of a 1kW fuelcell power system was developed and some tests like the load’s step changing were done on it. The results show that when a step changes with half load, the 1kW fuelcell power system’s variation of the bus voltage is less than 5V and the settling time is less than 25μs; the system works normally and steadily in the whole running process, and it can meet the spacecraft’s space application demand.
