PURPOSE:To prevent a speed from decreasing in absorptive storage of hydrogen and its emission, by inserting a porous metallic pipe into a metallic vessel having a hydrogen emitting port while containing a hydrogen absorptively storing alloy dust between the vessel and the metallic pipe and connecting a hydrogen supply pipe with the metallic pipe. CONSTITUTION:A hydrogen storage vessel, when it stores hydrogen, first closes valves 8, 9 and introduces the hydrogen into a hydrogen supply pipe 6 by opening a valve 10. The hydrogen, passing through a fine hole in a porous metallic pipe 4, is absorptively stored in a hydrogen absorptively storing alloy. If the hydrogen in the hydrogen absorptively storing alloy is placed in a saturated condition, the valve 10 is closed. Next the vessel, when it releases the hydrogen, opens the valves 8, 9, being heated as necessary. In this way, the vessel, allowing the hydrogen to flow in a manner of one-way from the inside to the outside of the porous metallic pipe 4, almost preventing a fine dust of the hydrogen absorptively storing alloy from blocking the fine hole of the porous metallic pipe. |
