摘要： A hydrogen supply method includes a two-side heat exchange mode in which both introducing a second fluid into a hydrogen storage part after the second fluid exchanges heat with a first fluid in a second heat exchanger in a state in which a compressor is driven to compress the first fluid and introducing the second fluid into the hydrogen storage part after the second fluid is heated or cooled in a thermal device are performed. The method also includes a one-side heat exchange mode in which one of introducing the second fluid into the hydrogen storage part after the second fluid exchanges heat with the first fluid in the second heat exchanger in a state in which the compressor is driven to compress the first fluid and introducing the second fluid into the hydrogen storage part after the second fluid is heated or cooled in the thermal device is performed.

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.
