Hydrogen storage device using column-shaped hydrogen storage metal

A hydrogen storage device is disclosed. The hydrogen storage device comprises: a cylinder-shaped storage container; a porous accommodating member accommodated in an inner space of the storage container; a column-shaped hydrogen storage metal of which the axial direction of the column shape is disposed parallel to the axial direction of the storage container such that the hydrogen storage metal is accommodated inside the storage container while being surrounded by the porous accommodating member; a hydrogen supply pipe connected to the storage container so as to enable fluid to flow therebetween, thereby supplying hydrogen to the inner space of the storage container; a hydrogen discharge pipe connected to the storage container so as to enable the fluid to flow therebetween, thereby discharging the hydrogen inside the storage container to a supply site; and a heat supply source positioned inside or outside the storage container so as to supply heat to the inner space of the storage container. When the hydrogen storage device is used, metal hydrides can be uniformly distributed in the inner space of the container, thereby enabling hydrogen to be quickly stored and discharged.
