Abstract
The hydrogen supply device includes a liquid hydrogen pump that boosts the pressure of liquid hydrogen stored in a liquid hydrogen tank, a vaporizer that converts the liquid hydrogen discharged from the liquid hydrogen pump into hydrogen gas, a pressure chamber that a hydrogen gas that flows out from the vaporizer is filled with and that supplies the filled hydrogen gas to a hydrogen engine, and a pump control unit. The pump control unit controls the discharge flow rate of the liquid hydrogen pump so that the actual pressure in the pressure chamber becomes a target pressure based on the hydrogen flow rate supplied to the hydrogen engine, the actual pressure in the pressure chamber, and the rotation speed of the hydrogen engine. At the same time, the target pressure of the pressure chamber is changed according to the rotation speed of the hydrogen engine.
