Abstract:
A hydrogen gas cooled hydrogen storage unit comprising:a storage unit casing, a plurality of hydrogen storage alloy rods disposed within said storage unit casing; a hydrogen flow channel region provided within said casing, between said hydrogen storage alloy rods, said flow channel region providing pathways between said hydrogen storage alloy rods to allow for high speed hydrogen gas flow, a portion of said hydrogen being stored within said storage material and releasing heat of hydride formation and the remainder of said hydrogen flowing through said hydrogen flow channels at a sufficient mass flow rate to remove said heat of hydride formation; a porous encapsulant surrounding said hydrogen storage alloy rods, thereby preventing said hydrogen storage alloy from being entrained into said high speed hydrogen gas flow.
