  • Publication number: 20040031387
    Abstract: A hydrogen storage medium is provided, where the medium is comprised of boron oxide and closely related compounds such as orthoboric acid, metaboric acid, hydrated boric acid, and disodium borohydrate. The medium is substantially an amorphous glassy network, albeit with local regions of order, pores, and networks that provide surface area. Hydrogen is adsorbed by the medium with a heat of adsorption of about 9 kJ/mol to about 13 kJ/mol, a value which is higher than that of the heat of adsorption of hydrogen on carbon. The value for the heat of adsorption of hydrogen on the inventive storage medium is provided by computation, and corroborated by experimental observation. The higher heat of adsorption of the medium provides for operation at temperatures higher temperatures higher than those provided by carbon.

  • Patent number: 6638348
    Abstract: The object of the invention is to provide a high performance metal hydride tank apparatus, which is capable of discharging the hydrogen gas stored in the metal hydride in the tank from throughout the metal hydride efficiently and rapidly. In the process of the hydrogen gas discharge, the metal hydride contained near the inner circumferential surface of the tank absorbs the heats by the temperature raised tank and starts discharging the hydrogen gas. The discharged hydrogen gas absorbs the heat from the inner circumferential wall efficiently, flowing along the inner circumferential wall rapidly guided by the cylinder-like baffle. Further, the discharged hydrogen gas flows through the hydrogen gas flow channel, which is formed into sections by the cylinder-like baffle in the tank, and travels throughout the metal hydride, thus heating up the metal hydride rapidly and discharging the hydrogen gas efficiently from throughout the alloy.

    Abstract: A hydrogen storage unit which uses hydrogen storage alloys to store hydrogen, and more particularly a heat transfer management/compartmentalization system for use in such system. The hydrogen storage alloy may be divided into compartments, separated by discs, further divided into sub-compartments by a flapper wheel. The discs and flapper wheel provide for optimal heat transfer throughout the system. The compartmentalization of the vessel may prevent compaction of the hydrogen storage alloys, which could lead to excessive strain on the vessel causing damage, deformation, or rupture of the vessel.

  • Patent number: 6539726
    Abstract: A thermal barrier for a Dewar vessel combines an insulative vapor plug and a vapor barrier. The plug is sized so as to define an open space between it and the neck portion of the Dewar vessel to allow venting of vaporous cryogen from the inner vessel of the Dewar vessel through a Dewar opening. The vapor barrier provides an interference between the plug and the neck portion that disrupts venting of vaporous cryogen but does not form an airtight seal that would block venting and cause unacceptable build-up of pressure within the inner vessel. Multiple vapor barriers, especially four or more, provide multiple interferences that create multiple chambers between the plug and the neck portion. Each interference disrupts migration of vaporous cryogen as an incremental increase (e.g., 2 psig or less) in vapor pressure of each chamber causes the chamber to breach and then another incremental increase in vapor pressure of the liquid cryogen in the vaporous state is required to breach each successive chamber.
