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 Li . The Ca Li is formed by melting amounts of elemental lithium and calcium together by induction heating in an argon atmosphere. The Ca Li 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 Li hydride may be used in a variety of applications as a hydrogen fuel and the Ca Li alloy may be used as a desiccant for removing moisture from hydrogen or hydrogen containing streams.
