Abstract: Electrochemical and thermal hydrogen storage alloy compositions that provide superior performance, including an electrochemical hydrogen storage alloy that provides superior low temperature discharge characteristics. The alloy compositions include microstructures in the interface region that are highly porous and that include catalytic metallic particles. The microstructures include a large volume fraction of voids having spherical or channel-like shapes and are sufficiently open structurally to facilitate greater mobility of reactive species within the microstructure and in the vicinity of catalytic metallic particles. Greater accessibility to reactive sites accordingly results. The greater mobility of reactive species and/or the greater density of catalytic particles lead to faster kinetics and improved performance (e.g. higher power), especially at low operating temperatures.

Abstract: A base-facilitated reformation reaction. Hydrogen is produced from a reaction of an organic substance with a base to form bicarbonate ion or carbonate ion as a by-product. The base-facilitated reformation reactions are thermodynamically more spontaneous than conventional reformation reactions and are able to produce hydrogen gas at less extreme reaction conditions than conventional reformation reactions. In one embodiment, the instant base-facilitated reactions produce hydrogen gas from an organic substance at a lower temperature than is possible for the production of hydrogen gas from the organic substance in a conventional reformation reaction. In another embodiment, the instant base-facilitated reformation reactions produce hydrogen gas from an organic substance at a faster rate at a particular temperature than is possible from the conventional reformation reaction of the organic substance.

Abstract: A process for producing hydrogen gas from a reaction of an organic substance and a base with a recycling of a carbonate or bicarbonate by-product and a regeneration of the base. In one embodiment, reaction of an organic substance and a base produces hydrogen gas and a metal carbonate. The instant invention provides recycling of the metal carbonate by-product. In a preferred embodiment, the metal carbonate by-product is soluble and recycling includes a three step process. In a first step, the soluble metal carbonate is reacted with a metal hydroxide to form a weakly soluble or insoluble metal carbonate that precipitates in a metathesis reaction. The metal hydroxide reactant of the hydrogen producing reaction is also formed in the metathesis reaction and remains in solution. Precipitation of the carbonate thus permits ready isolation of the carbonate by-product, while leaving behind an aqueous metal hydroxide phase that can be returned to and further utilized in the hydrogen producing reaction.
