The invention provides a fuel cell waste heat utilization system and a control method thereof, and relates to the technical field of fuel cells. The fuel cell waste heat utilization system comprises an electric pile, a water pump, a heater, a radiator, a flow direction control valve, an expansion water tank, a heat exchanger, a deionization tank, a first valve, a second valve and a third valve, the electric pile, the water pump, the radiator, the flow direction control valve and the third valve form a main flow path, and the electric pile, the water pump, the heater, the flow direction control valve and the third valve form a main heating flow path. The water pump, the heater, the flow direction control valve, the second valve and the heat exchanger form a warm air heating flow path, and the water pump, the first valve and the heat exchanger form a waste heat flow path. The warm air system and the fuel cell system share one set of heater, water pump and expansion water tank, so that the integration degree of the whole vehicle and the fuel cell warm air cooling system is improved, the space of the whole vehicle is saved, the cost of the whole vehicle is reduced, the energy consumption of the vehicle is reduced, and the energy utilization rate is improved.
