Beschreibung
Zusammenfassung:	This hydrogen re-liquefaction system re-liquefies boil-off gas produced in a liquid hydrogen tank into liquid hydrogen and returns the liquid hydrogen to the liquid hydrogen tank, and includes: a delivery passage through which hydrogen to be delivered from the liquid hydrogen tank to a supply destination flows; a re-liquefaction passage through which the boil-off gas flows; and a re-liquefaction device that cools the boil-off gas flowing through the re-liquefaction passage and condenses the boil-off gas. The re-liquefaction device is a magnetic refrigerator that includes: a condenser provided in the re-liquefaction passage; and a heat dissipator provided in the delivery passage, cools the boil-off gas via the condenser by demagnetization, and releases heat generated during magnetization to the hydrogen via the heat dissipator.
