摘要
采用质子交换膜燃料电池(PEM FC)与人力相结合的动力系统,设计出一种仅由PEM FC供电的电动车。该系统针对PEM FC在电动车启动、爬坡时输出功率不能很好满足车辆要求的特性,采用人力补偿及合理的控制策略使PEM FC在高效率下运行,克服PEM FC作为独立电源供电的不足。理论分析和实物运行结果表明,该系统具有较高的能量效率和良好的运行稳定性。
In this paper,an electric vehicle powered by proton exchange membrane fuel cell（PEMFC） was designed.Combined with manpower,PEMFC made up the energy system as a single power supply.Because the output power of PEMFC could not meet the requirements when the electric vehicle began to start and climb,the manpower compensation and reasonable control strategy were used to make PEMFC work in the high efficiency area to overcome the deficiencies of PEMFC as a single power supply.The theoretical analysis and experimental results show that the system has high energy efficiency and good stability.
