The invention relates to the technical field of fuel cells, in particular to a fuel cell system, an automobile and a power supply control method. The fuel cell system comprises a fuel cell, a fuel cell main DCDC, a power cell, a power distribution device, a bridging loop and a vehicle control unit VCU; the fuel cell is connected with the power distribution device through the fuel cell main DCDC; the power cell is connected with the power distribution device; and the bridging loop is connected in parallel with the fuel cell main DCDC. According to the fuel cell system provided by the embodiment of the invention, the bridging loop is connected in parallel at the main DCDC position of the fuel cell, when the voltage difference between the fuel cell and the power cell is small, the bridging loop is connected, and the main DCDC of the fuel cell stops working, so that the working efficiency of the main DCDC of the fuel cell is improved, the power consumption of the whole vehicle is reduced, and the driving range is increased.

    本发明涉及燃料电池技术领域,尤其涉及一种燃料电池系统、汽车及供电控制方法,燃料电池系统包括:燃料电池、燃料电池主DCDC、动力电池、配电装置、桥接回路和整车控制器VCU;燃料电池通过燃料电池主DCDC与配电装置连接;动力电池与配电装置连接;桥接回路与燃料电池主DCDC并联。本发明实施例提供的燃料电池系统,通过在燃料电池主DCDC位置并联桥接回路,当燃料电池与动力电池电压差较小时,接通桥接回路,燃料电池主DCDC停止工作,提高燃料电池主DCDC工作效率,减少整车电耗,提高续驶里程。
