HYDROGEN SUPPLYING DEVICE AND HYDROGEN ENGINE VEHICLE

A hydrogen supplying device (30) includes a liquid hydrogen pump (32), an evaporator (37), a pressure chamber (45) configured to be filled with hydrogen gas flowing therein from the evaporator (37) and to supply the filled hydrogen gas to a hydrogen engine (10), and a pump control unit (80) configured to adjust a discharge flow rate of the liquid hydrogen pump (32) based on both a flow rate of hydrogen to be supplied to the hydrogen engine (10) and an actual pressure in the pressure chamber (45).
