Abstract: In one aspect, the invention provides a hydrogen storage composite formed of a mesoporous scaffolding material and a hydrogen storage composition comprising precursors that react to form quarternary B—H—Li—N composition. In another aspect, the invention provides a process for forming hydrogen storage material. In each aspect, a high portion of hydrogen is released as hydrogen gas and a lesser portion of hydrogen is released as a hydrogen-containing byproduct.

Abstract: In one aspect, the invention provides a hydrogen storage material that is formed by reacting solid precursors (a) and (b). The (a) precursor is a compound containing X—H and Y—H bonds, where X is a Group 13 and Y is a Group 15 element. Preferably X is boron (B—H) and Y is nitrogen (N—H). Most preferably, the precursor (a) is borazane. The (b) precursor is preferably a hydride, such as LiH or LiAlH4. Another feature of the present invention is a novel hydrogen storage composition material that is formed as an intermediate (INT) in the reaction of the (a) with the (b) precursors. The INT hydrogen storage material can be a quaternary B—H—Li—N composition. Other aspects of hydrogen storage materials are provided herein.

Abstract: In one aspect, the invention provides a method of storing hydrogen that comprises reacting two precursors to form a hydrogen storage composition comprising hydrogen, nitrogen, a Group 13 element, and an element selected from Group 1, Group 2 or mixtures thereof. In other aspects, the present invention provides a method of storing hydrogen by ball-milling two precursors at a temperature in a range sufficient to prevent pre-mature release of hydrogen, while the temperature is still sufficient to induce reaction between the precursors. The precursors preferably have X—H, Y—H and A-H bonds where X represents a Group 13 element, Y represents a Group 15 element, and A represents an element from Group 1, Group 2, or mixtures thereof. Other variations of the methods of storing hydrogen are further provided.

Abstract: In one aspect, the present invention provides a system for methods of producing and releasing hydrogen from hydrogen storage compositions having a hydrogenated state and a dehydrogenated state. In the hydrogenated state, such a composition comprises a hydride and a hydroxide. In a dehydrogenated state, the composition comprises an oxide. A first reaction is conducted between a portion of the hydride and water to generate heat sufficient to cause a second hydrogen production reaction between a remaining portion of the hydride and the hydroxide.

Abstract: A technique for rejecting heat from a fuel cell stack. Heated stack coolant from the fuel cell stack is directed to a heat pump module where it is compressed to raise its temperature. The heated and compressed coolant is then directed through a radiator that cools the coolant through interaction with ambient air. The coolant is then sent through an expansion aperture to reduce its pressure, and thus, further reduce its temperature before it is sent back to the fuel cell stack to collect waste heat therefrom. The heated and compressed coolant can be sent to hydride bed to release hydrogen therefrom before it is sent to the radiator. In one embodiment, the coolant is hydrogen.

Abstract: A business method intended to partner furniture manufacturers, carpenters, craftsmen, artisans, and bed and breakfast, country inns and small hotels to showcase both businesses equally. The business method allows growth of both the bed and breakfast inns and the furniture manufacturers, by directed advertising through web sites and real life display and use of the furniture. The method brings museum replica fine furniture to the use of small inns giving both companies the added advertising power of linked sites. The method allows all bed and breakfast”s rooms to become possible furniture showrooms, whether the piece is actually produced by an associated craftsman or is a real antique that can be replicated by the craftsmen. Bed and breakfasts, country inns and small hotels can expand their services to include furniture sales and the craftsmen, artisans, and carpenters have additional showrooms for their work.
