Abstract:
A hydrogen gas cooled hydrogen storage element comprising:a hydrogen storage alloy bed including a hydrogen storage alloy; a plurality of distinct and adjacent hydrogen flow through channels provided within said hydrogen storage alloy bed, said flow through channels each having an input and an output, said flow through channels providing pathways through said hydrogen storage alloy bed, said pathways being adapted to allow a high speed gaseous hydrogen stream to flow through said hydrogen storage alloy bed, whereby a portion of said high speed gaseous hydrogen stream is stored within said hydrogen storage alloy thereby releasing heat of hydride formation, and the remainder of said high speed gaseous hydrogen stream flowing through said hydrogen storage bed at a mass flow rate sufficient to remove the heat of hydride formation; and a porous encapsulant surrounding said hydrogen storage alloy, thereby preventing said hydrogen storage alloy from being entrained into said high speed hydrogen gas flow.
