摘要： Disclosed is a hydrogen storing method having improved energy efficiency by efficiently reusing heat through a heat circulation structure. Specifically, the hydrogen storing method includes supplying hydrogen by the supply device, compressing hydrogen received from the supply device by a compression device, receiving the hydrogen compressed by the compression device and storing the same in a storage device, and transferring heat generated from the storage device to the compression device, wherein the compression device and the storage device each include solid state hydrogen storage materials that cause an exothermic reaction when hydrogen is stored and an endothermic reaction when hydrogen is released.

摘要： A solid hydrogen storage device is provided and has a shape in which a polygonal cross section extends in a longitudinal direction. The device includes a plurality of heat exchange tubes having heat transfer fluid flowing therein and are disposed inside the storage device in a polygonal shape corresponding to the cross section of the storage device while extending in the same direction as an extending direction of the storage device. A hydrogen storage body is disposed inside the storage device to absorb or release heat through a reaction that releases or bonds with hydrogen and to exchange heat with the heat exchange tubes.
