The invention discloses a cooling system of an automobile fuel cell. The cooling system comprises a water pump, a first control valve, a heating device, a heat dissipation device, a warm air device, an expansion water tank, a first temperature sensor, a second control valve and a controller. A water outlet of the water pump is connected with a water inlet of the fuel cell; a water inlet of the water pump is connected with water outlets of the heating device, the heat dissipation device, the warm air device and the expansion water tank, water inlets of the heating device, the heat dissipation device, the warm air device and the expansion water tank are connected with four outlets of the first control valve, and the inlet of the first control valve is connected with the water outlet of the fuel cell; the first temperature sensor is located at the water outlet of the water pump; and the water outlet of the expansion water tank is connected with the water inlet of the water pump through asecond control valve. In the invention, a path of a cooling liquid from the heat dissipation device to the fuel cell is shortened so that a response speed of the fuel cell is improved. In addition, the invention further discloses a control method of the cooling system and an automobile.

    本发明公开一种汽车燃料电池的冷却系统,该冷却系统包括水泵、第一控制阀、加热装置、散热装置、暖风装置、膨胀水箱、第一温度传感器、第二控制阀以及控制器,水泵的出水口与燃料电池的进水口连通,水泵的进水口分别与加热装置、散热装置、暖风装置和膨胀水箱的出水口连通,加热装置、散热装置、暖风装置和膨胀水箱的进水口还分别与第一控制阀的四个出口连通,第一控制阀的入口与燃料电池的出水口连通;第一温度传感器位于水泵的出水口处;膨胀水箱的出水口通过第二控制阀与水泵的进水口连通。本发明缩短了冷却液由散热装置至燃料电池的路径,从而有利于提高燃料电池的响应速度。此外,本发明还公开一种冷却系统的控制方法及汽车。
