PURPOSE:To prevent deterioration of hydrogen storing characteristic of a hydrogen storage metal due to pulverization of hydrogen storage metal and to prevent deformation of a vessel for the hydrogen storage metal due to expansion of the metal during occlusion of hydrogen by supporting metal particles having hydrogen storage capacity on a carrier comprising porous calcium silicate and moulding the metal particles together with the carrier. CONSTITUTION:(I) Metal particles capable of having hydrogen storage capacity are dispersed in a slurry somprising slaked line and diatomaceous earth in a vessel main body. (II) Then, a supporting body comprising porous solid calcium silicate is formed by allowing CaO to react with SiO2. Further, (III) the metal particles dispersed in the supporting body is treated to acquire hydrogen storage capacity to prepare thus a moulded body of the hydrogen storage material. When the slurry (I) is prepd., slaked line is mixed with diatomaceous earth to 0.6-1.0 proportion of CaO/SiO2. It is preferred to mix 10-20wt% (basing on the whole solid component) asbestos, glass fiber, or heat resistant fiber with the above described slurry.
