Abstract:
The present invention relates to a hydrogen storage material and a process for preparing the same. The invention provides a polymer-transition metal hydride complex which can safely and reversibly store hydrogen in a high capacity, and a process for preparing the same. More specifically, the invention relates to a polymer- transition metal hydride complex wherein a transition metal hydride is bonded to the aromatic ring of a homopolymer or a copolymer of a monomer comprising an aromatic ring, a process for preparing the same, a hydrogen storage material and a hydrogen storage device comprising the same. The transition metal may be titanium (Ti), vanadium (V) or scandium (Sc), which is capable of Kubas binding with hydrogen.

Abstract:
A closure (40) for a container incorporates calcium hydride and a matrix material as a hydrogen-generating composition. In use, hydrogen is generated which reacts with oxygen permeating a container associated with the closure and a catalyst associated with the container catalyses reaction of the hydrogen and oxygen to produce water, thereby scavenging the oxygen. The composition of calcium hydride and matrix is also claimed.
