ABSTRACT:
A nonequilibrium state material, typically a rare-earth-transition metal, for reversible hydrogen storage. A rare earth-transition metal such as a rare earth cobalt alloy, like a samarium-cobalt or a lanthanum-nickel alloy, is provided in the amorphous or metastable crystalline state as a hydrogen absorbing material, particularly for use in a hydrogen storage and retrieval system, such as a fluidized bed or stacked plate hydrogen storage cell. The rare-earth-transition metal material is rapidly cooled from the liquid state to avoid the transition to a full crystalline state thereby obtaining an amorphous or quasi-stable crystalline state material which has the property of enhanced hydrogen storage capacity as well as being substantially immune to fracturing.
