Abstract
A nonreversible metal hydride for use as a hydrogen fuel. The nonreversible metal hydride is formed from an intermetallic compound having the formula Ca.sub.1+a Li.sub.2+b. The Ca.sub.1+a Li.sub.2+b is formed by melting amounts of elemental lithium and calcium together by induction heating in an argon atmosphere. The Ca.sub.1+a Li.sub.2+b is cooled and crushed into a powder. The alloy powder is subsequently hydrogenated at ambient temperatures or lower. Resulting is a metal hydride having exceptional reactivity to water during hydrolysis due to its nano-crystalline structure. Dehydrogenation of the metal hydride does not regularly occur due to the absorbed hydrogen being chemically bonded to the lithium and calcium. The Ca.sub.1+a Li.sub.2+b hydride may be used in a variety of applications as a hydrogen fuel and the Ca.sub.1+a Li.sub.2+b alloy may be used as a desiccant for removing moisture from hydrogen or hydrogen containing streams.
