PURPOSE:To get a vessel, whose actual capacity and hydrogen absorbing volume to contain are the same, by setting a filter which has flexibility to absorb the expansion of the volume of a hydrogen storage metal, at absorbing of hydrogen, and which can prevent the flow of the metal powder, in the vessel. CONSTITUTION:A pipe body 14 which functions as a flow route for hydrogen, is connected through the center part of a cover body 12 of a vessel 10. A filter 16 is formed of a material which is flexible and inert to hydrogen, such as a ceramic fiber, and accepted in a cylindrical wire-netting 18 to keep its shape. This vessel 10 formed with the filter 16 accepted in the cylindrical wire-netting 18, is filled up with proper quantity of powder 20 of hydrogen storage metal, and at this time, this powder 20 of the hydrogen storage metal is filled into the space in the vessel 10 except the filter 16, as the vessel 10 is almost full. |
