<P>PROBLEM TO BE SOLVED: To provide a hydrogen storage device of large hydrogen occlusion amount per a unit volume, in addition to the comparative low cost and lightweight. <P>SOLUTION: This hydrogen storage device is composed of a vessel and a hydrogen occluding body accommodated in the vessel, and the hydrogen occluding body accommodated in the vessel includes a porous carbon material having a specific surface area of 1000 m<SP>2</SP>/g or more, and hydrogen occlusion alloy. As the hydrogen occluding body includes the porous carbon material of high heat conductivity, the heat generation in accompany with the hydrogen occlusion is small, and further as the hydrogen occluding alloy is also included, a bulk density of the hydrogen occluding body is increased, and the hydrogen storage device of high hydrogen occlusion amount per a unit volume is provided. <P>COPYRIGHT: (C)2003,JPO |
