Abstract : An object of the present invention is to provide a solid-state hydrogen storage material that does not require high pressure for efficient absorbtion or high temperature for efficient discharge. A further object of the present invention is to provide a solid-state hydrogen material that is not impaired by atmospheric exposure and that does not discharge hydrogen at room temperature. The above and other objects are achieved in the present invention which comprises a layer of an amorphous binary alloy of a lanthanide and iron, nickel or cobalt disposed on a suitable substrate and overcoated with a palladium metal layer. The present invention adsorbs hydrogen at low pressures, resists surface poisoning, stores hydrogen at room temperature, and discharges hydrogen by heating the storage material to a relatively moderate temperature.
