20100160149 | METHOD OF ACTIVATING OR REGENERATING A HYDROGEN STORAGE MATERIAL - 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. | 06-24-2010 |
