The invention discloses a fuel cell hybrid power system, which comprises a fuel cell module, a charging control module, a charging selection module, a discharging selection module, an MCU control module and a plurality of rechargeable batteries, and is characterized in that the MCU control module obtains the voltage of each rechargeable battery, and when the voltage of a certain rechargeable battery is lower than a set value, the MCU control module controls the charging selection module and the discharging selection module; when the rechargeable battery supplies power to the load, the rechargeable battery stops supplying power and is switched to other rechargeable batteries for supplying power at the same time, the fuel battery module and the charging control module are enabled, and the charging control module carries out boosting and current limiting processing on electric energy output by the fuel battery module and charges the rechargeable battery. The rechargeable battery can provide the required load power in time when the load is required to be high, the rechargeable battery does not need to wait when being started, and the fuel cell module only needs to keep stable operation power, so that the fluctuation of the power of the fuel cell is avoided, and the load can be quickly responded.
本发明公开了一种燃料电池混合动力系统,包括燃料电池模块、充电控制模块、充电选择模块、放电选择模块、MCU控制模块以及多块可充电电池,MCU控制模块获取各可充电电池的电压,当有可充电电池的电压低于设定值时,使该可充电电池停止供电、同时切换为其它可充电电池供电,并且使能燃料电池模块和充电控制模块,所述充电控制模块将燃料电池模块输出的电能进行升压及限流处理,给该可充电电池充电,在本发明采用可充电电池为负载供电,可充电电池能够在负载高需求时及时提供所需负载功率,可充电电池在启动时无需等待,而燃料电池模块只需保持稳定的运行功率,避免了燃料电池功率的波动,从而能够对负载进行快速响应。
