Abstract
A hydrogen supplying device includes a liquid hydrogen pump, an evaporator, a pressure chamber configured to be filled with hydrogen gas flowing therein from the evaporator and to supply the filled hydrogen gas to a hydrogen engine, and a pump control unit configured to adjust a discharge flow rate of the liquid hydrogen pump based on both a flow rate of hydrogen to be supplied to the hydrogen engine and an actual pressure in the pressure chamber.
