Zusammenfassung:	The present disclosure relates to a hydrogen liquefaction device capable of liquefying gaseous hydrogen into a liquid state through multi-stage cooling by heat exchange between a heat pipe in which a refrigerant cooled by a cryocooler flows and hydrogen flowing through a micro-channel. The device may comprise a hydrogen pipe for connecting a hydrogen supply unit in which gaseous hydrogen is stored and a storage container in which liquid hydrogen liquefied in a liquid state is stored; and a heat exchange unit that cools hydrogen by at least one or more heat exchangers installed on the hydrogen pipe so that hydrogen being introduced from the hydrogen supply unit and flowing through the hydrogen pipe toward the storage container can be cooled and liquefied in a process of passing through the hydrogen pipe and be discharged to the storage container as liquid hydrogen.
