摘要:
The present invention concerns a method of activating or regenerating a hydrogen storage material which contains at least one metal hydride. The at least one metal hydride is brought into contact with an inert solvent and the inert solvent is subsequently removed again. After contacting with and removal of the inert solvent, there is not only an increase in the reaction rate but surprisingly the hydrogenation also proceeds more completely. The present method is particularly advantageous when the hydrogen storage material contains at least components which interact with one another during absorption and desorption.

The invention relates to a metal-containing, hydrogen-storing material which contains a catalyst for the purpose of hydration or dehydration, said catalyst being a metal carbonate. The method for producing such a metal-containing, hydrogen-storing material is characterized by subjecting the metal-containing material and/or the catalyst in the form of a metal carbonate to a mechanical milling process.

The invention relates to a metal-containing, hydrogen-storing material that contains a catalyst for hydrating or dehydrating the same. The catalyst is at least one organic compound. The invention also relates to a method for the production of a metal-containing, hydrogen-storing compound, which is characterised in that the metal-containing material and/or the catalyst, which are in the form of an organic compound, is/are subjected to a mechanical grinding process.

The invention relates to a composite material storing hydrogen. Said composite material can alternate, in an essentially reversible manner, between a storage state and a non-storage state and optionally at least on intermediate state. In the storage state thereof, the system comprises the following constituents: (a) at least one first hydride constituent and (b) at least one second constituent that is at least one hydrogen-free constituent and/or one other hydride constituent. The at least one first hydride constituent and the at least one second constituent are in a first solid multiphase system, and during the changeover to the non-storage state of the system, the at least one first hydride constituent reacts with the at least one second constituent, forming H2, in such a way that, in the non-storage state, at least one other hydrogen-free compound and/or alloy is formed and another solid multiphase system is created.
