de Pous, O

A magnesium powder composition is used in a method for the reversible storage of hydrogen by absorption thereof in the magnesium to form the hydride which consists of an intimate mixture of magnesium powder and an inert powder which is stable under the conditions of formation and decomposition of the hydride. The stable inert powder, which prevents the agglomeration of the magnesium powder and maintains its hydrogen-storage capacity, is selected from the group which consists of metal powders such as manganese, iron, cobalt, nickel and copper, metal alloy powders such as iron-zinc alloys, and the oxides, carbides or nitrides of magnesium, calcium, boron, aluminum, silicon, titanium, zinc, vanadium, chromium, manganese and iron. The mixture is formed by intimately grinding the magnesium and inert powders together.
