Solid-State Hydrogen Storage Device

Abstract

A solid-state hydrogen storage device includes a steel cylinder accommodating a ceramic sintered body that has fine open spaces therein for storing hydrogen, a housing, which houses the steel cylinder, and a fire-retarding stuffing material stuffed in the housing around the steel cylinder for protection.

1 . A solid-state hydrogen storage device comprising:
 a steel cylinder, said steel cylinder comprising gas inlet pipe extending from a first end thereof for connection to a hydrogen supply source, a first control switch installed in said gas inlet pipe for controlling input of hydrogen into said steel cylinder, a gas outlet pipe extending from a second end thereof, and a second control switch installed in said gas outlet pipe for controlling output of hydrogen out of said steel cylinder through said gas outlet pipe;   wherein:   the solid-state hydrogen storage device further comprises:   a ceramic sintered body accommodated in said steel cylinder, said ceramic sintered body having fine open spaces therein for storing hydrogen;   a housing, which houses said steel cylinder, and   a stuffing material stuffed in said housing around said steel cylinder.   
     
     
         2 . The solid-state hydrogen storage device as claimed in  claim 1 , wherein said housing is made out of a metal selected from one of the materials including stainless steel, aluminum, aluminum alloy and iron. 
     
     
         3 . The solid-state hydrogen storage device as claimed in  claim 1 , wherein said stuffing material is a fire retardant material. 
     
     
         4 . The solid-state hydrogen storage device as claimed in  claim 1 , wherein said housing has two through holes through which said gas inlet pipe and said gas outlet pipe of said steel cylinder extend out of said housing. 
     
     
         5 . The solid-state hydrogen storage device as claimed in  claim 1 , wherein said housing has two through holes through which said first control switch and said second control switch of said steel cylinder extend out of said housing.
