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.
