When hydrogen is taken out, para-hydrogen having a low energy is converted into ortho-hydrogen having a high energy, and the cooling effect due to the endothermic para-ortho conversion is utilized for maintaining a low temperature within a hydrogen storage device 10. A hydrogen storage device 10 for storing liquid hydrogen 21 is provided to achieve the above, wherein a porous magnetic body serving as a para-ortho conversion catalyst is arranged in a hydrogen flow opening 13.
L~invention concerne un dispositif de stockage d~hydrogène, selon lequel, lorsque de l~hydrogène est prélevé, un para-hydrogène de faible énergie est transformé en un ortho-hydrogène de haute énergie, l'effet endothermique refroidissant de la transformation para-ortho étant utilisé pour maintenir la température dans le dispositif de stockage d~hydrogène (10) basse. L'obtention d'un tel système a lieu en utilisant un dispositif de stockage d'hydrogène (10) destiné au stockage d~hydrogène liquide (21), un corps magnétique poreux servant de catalyseur de la transformation para-ortho étant disposé dans une ouverture de circulation de l~hydrogène (13).
