Abstract: A system for supplying hydrogen using waste heat of a fuel cell includes: a fuel cell to produce electric power using hydrogen; an internal cooling line in which a cooling medium flows and configured to pass through the fuel cell while cooling the fuel cell with the cooling medium; a solid hydrogen storage provided on a downstream side of the fuel cell on the internal cooling line and configured to discharge the hydrogen through absorption of waste heat of the heated cooling medium and to supply the discharged hydrogen to the fuel cell; and a hydrogen supply line to connect the solid hydrogen storage and the fuel cell and to supply the discharged hydrogen. In particular, the internal cooling line is reconnected to the fuel cell after passing through the solid hydrogen storage and provides the cooled cooling medium to the fuel cell.

Abstract: 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.
