The invention provides a heat dissipation device of a vehicle-mounted fuel cell engine, belongs to the technical field of fuel cells, and solves the problem that heat energy and tail water generated by a system are not reasonably utilized in the prior art. The device comprises an electric pile, a main radiator, first and second heat exchangers, first to fourth water pumps, water storage equipment and a controller. Wherein a cooling liquid outlet of the galvanic pile is connected with a cooling liquid inlet of the galvanic pile through the water pump I, a branch I of the heat exchanger II, a branch I of the heat exchanger I and the main radiator in sequence; a drainage end of the water diversion structure is connected with a water inlet of the water storage equipment through a fourth water pump; the water storage equipment is arranged inside the carriage, a water circulating pipeline communicated with the heat exchanger I and the water pump II is arranged outside, and a heat preservation structure for storing hot water is arranged inside; a second branch of the second heat exchanger is connected with an air heater core of the vehicle-mounted air conditioner through a third water pump. The controller is used for controlling starting and stopping of the second water pump to the fourth water pump and controlling the opening degree of an outlet valve of the water storage device, and hot water capable of being directly used is obtained.
