The invention provides a fuel cell heat dissipation control system and an engine thereof, belongs to the technical field of fuel cells, and solves the problem that the heat dissipation capability of a fuel cell cannot be accurately evaluated and dynamically controlled. The system comprises a radiator provided with a fan, a thermostat, an electric pile, a temperature sensor and a controller. The first input end of the thermostat is directly connected with the cooling liquid outlet of the electric pile, the second input end is connected with the cooling liquid outlet of the electric pile through the radiator, and the output end is connected with the cooling liquid inlet of the electric pile. And the temperature sensor is arranged on the inner wall of the pipeline at the cooling liquid inlet of the electric pile. The controller is internally provided with a fuel cell temperature control program for limiting the maximum output power of the electric pile and is used for executing the fuel cell temperature control program when the fuel cell runs; and regularly evaluating the heat dissipation capability of the radiator according to the data of the temperature sensor, and correcting the maximum output power of the electric pile in the temperature control program of the fuel cell in real time according to the evaluation result, so that the output power of the fuel cell in different scenes reaches the maximum.
