Abstract
Novel materials having the ability to reversibly store hydrogen are amorphous metal alloys of the formula EQU A.sub.a M.sub.b M'.sub.c wherein PA1 A is at least one metal selected from the group consisting of Ag, Au, Hg, Pd and Pt; PA1 M is at least one metal selected from the group consisting of Pb, Ru, Cu, Cr, Mo, Si, W, Ni, Al, Sn, Co, Fe, Zn, Cd, Ga and Mn; and PA1 M' is at least one metal selected from the group consisting of Ca, Mg, Ti, Y, Zr, Hf, Nb, V, Ta and the rare earths; and wherein PA1 a ranges from greater than zero to about 0.80; PA1 b ranges from zero to about 0.70; and PA1 c ranges from about 0.08 to about 0.95; characterized in that (1) a substantial portion of A is disposed on the surface of said material and/or (2) that said material functions as an active surface layer for adsorbing/desorbing hydrogen in conjunction with a bulk storage material comprising a reversible hydrogen storage material.
