<p>PURPOSE:To enable hydrogen gas to exchange heat with hydrogen absorbing alloy directly for shortening a time required for absorbing and exhausting hydrogen by sending hydrogen gas whose temperature is raised up to the prescribed level in a hydrogen gas heat exchanger into a storage vessel of hydrogen. CONSTITUTION:Hydrogen absorbing alloy 1 is filled up in about a half of a chamber 13 in a vessel 11 and it is arranged that when hydrogen gas is taken in or exhausted, the hydrogen absorbing alloy 1 is fluidized by hydrogen gas blowing up through a bottom filter 12a for making contact with hydrogen gas directly to be able to exchange heat with the gas efficiently. Hydrogen gas, not absorbed in the hydrogen absorbing alloy 1, is pressurized by a blower 3 after flowing out from the vessel 11 and mixed with feed hydrogen gas sent through a valve 7, and after passing through a valve 6, cooled in a hydrogen gas heat exchanger 2 by the third medium, for instance, from 30 deg.C to 20 deg.C and then sent into the vessel 11.</p> |
