A cooled-hydrogen supply station includes: a first coolant passage through which a first coolant circulates; a water-cooled refrigerator unit disposed on a part of the first coolant passage to cool the first coolant; a second coolant passage through which a second coolant flows; a first heat exchanger for cooling the second coolant by the first coolant, between another part of the first coolant passage and a part of the second coolant passage; a hydrogen storage unit; a hydrogen passage for transporting hydrogen stored in the hydrogen storage unit; and a second heat exchanger for cooling the hydrogen by the second coolant, between another part of the second coolant passage and a part of the hydrogen passage. The hydrogen is cooled down to a temperature of −43° C. to −20° C. by the second heat exchanger, and a hydrogen cooling power for cooling hydrogen to −40° C. is between 13.5 kW and 16.5 kW.
