Cathode with silver material and silicate dopant and method of producing

Methods and systems for hydrogen generation from solid hydrogen storage compositions which generate hydrogen in an exothermic reaction wherein the heat released can be absorbed by solid endothermic compositions are disclosed. The solid hydrogen storage compositions comprise mixtures of chemical hydrides and water surrogate compounds. Fuel cartridges suitable for use with compositions which generate hydrogen upon the application of thermal initiation and methods for operating the fuel cartridges are also disclosed.

Compositions, devices and methods for hydrogen generation

Techniques for packaging and utilizing solid hydrogen-producing fuel are described herein. The fuel may be in the form of a bonded/compressed powder, granules, or pellets. The fuel is packaged in cartridges having hydrogen-permeable enclosures. In operation, the fuel undergoes a hydrogen-releasing Thermally Initiated Hydrolysis (TIH) reaction. A cartridge may comprise one or more fuel chambers, and several cartridges may be assembled together.

Techniques for packaging and utilizing solid hydrogen-producing fuel

The present invention relates to the use of triborohydride salts as hydrogen storage materials. The present invention also relates to a system of using triborohydride salts to generate hydrogen gas for use in a fuel cell or other hydrogen-consuming device. A novel method of preparing triborohydride salts is also disclosed, wherein gaseous diborane is reacted with a carbonate suspended in a non-aqueous solvent in a suitable vessel with agitation. The process is typically carried out utilizing sodium carbonate to form sodium triborohydride. Other triborohydride salts can then be formed by cationic exchange. Hydrogen generating fuels according to the present invention include aqueous or hydroalcoholic solutions or slurries of a triborohydride salt, which may additionally contain a borohydride salt to provide operation over a broader temperature range.

Triborohydride salts as hydrogen storage materials and preparation thereof

The present invention relates to processes for producing borohydride compounds. In particular, the present invention provides efficient processes and compositions for the large-scale production of borohydride compounds of the formula YBH by the reaction of a boron-containing compound represented by the formula BX with hydrogen or an aldehyde to obtain diborane and HX, and reacting the diborane with a Y-containing base selected from those represented by the formula Y O, YOH and Y CO to obtain YBH and YBO . Y is selected from the group consisting of the alkali metals, pseudo-alkali metals, alkaline earth metals, an ammonium ion, and quaternary amines of the formula NR , wherein each R is independently selected from hydrogen and a straight- or branched-chain C alkyl group, and X is selected from the group consisting of halide ions, &mdash;OH, &mdash;R&prime; and &mdash;OR&prime; groups, chalcogens, and chalcogenides, wherein R&prime; is a straight- or branched-chain C alkyl group.

Processes for synthesizing borohydride compounds

Processes for synthesizing borohydride compounds with reduced energy requirements and high efficiency are disclosed. The processes include the reaction of a base with a borane complex or diborane to produce a borohydride compound of formula YBH , where Y is a monovalent cationic moiety.
