The invention relates to a liquefaction device (11) for liquefying gaseous dihydrogen produced by the evaporation of liquid dihydrogen (9) stored in at least one tank (3, 5). The liquefaction device (11) comprises: at least one heat exchanger (13); at least one supply branch (21) configured to convey at least a portion of the gaseous dihydrogen from the tank (3, 5) to the gaseous dihydrogen consumer (7), a portion of the supply branch passing through a heat exchanger inside which a catalyst (151) involved in the conversion of parahydrogen to ortho-hydrogen is placed; at least one cooling branch (23) comprising at least one compression member (25); a portion of the cooling branch (23) passing through the heat exchanger (13) exchanges heat with the first channel (15) in order to liquefy at least a portion of the dihydrogen circulating in the cooling branch and heat the dihydrogen circulating in the supply branch (21). 本发明涉及一种用于液化气态二氢的液化装置(11)，所述气态二氢由储存在至少一个罐(3，5)中的液态二氢(9)的蒸发产生。该液化装置(11)包括：至少一个热交换器(13)；至少一个供给支路(
