Abstract
A vehicle includes an internal combustion engine that uses hydrogen as fuel, a fuel tank that stores liquid hydrogen, and a vaporizer that vaporizes the liquid hydrogen stored in the fuel tank. The vehicle further includes multiple heat exchangers that exchange heat with the vaporizer, passages that connect the vaporizer to the respective heat exchangers, a flow rate control mechanism that controls a flow rate of a heating medium flowing through each passage, and a controller that controls the flow rate control mechanism. The heat exchangers include a radiator and a waste heat recovery device. The radiator is an engine heat exchanger that exchanges heat with a fluid flowing through the internal combustion engine. The waste heat recovery device exchanges heat with exhaust gas of the internal combustion engine.
