    • A hydrogen storage electrode comprising a body of an alloy of the general formula, AB a , or a hydride thereof in which A represents at least one element selected from the group consisting of Zr, Ti, Hf, Ta, Y, Ca, Mg, La, Ce, Pr, Mm, Nb, Nd, Mo, Al and Si, B represents at least one element selected from Ni, V, Cr, Mn, Fe, Co, Cu, Zn, Al, Si, Nb, Mo, W, Mg, Ca, Y, Ta, Pd, Ag, Au, Cd, In, Sn, Bi, La, Ce, Mm where Mm is a mixture of rare earth elements, Pr, Nd, Th and Sm provided that A and B are different from each other, and ª is a value of from 1.0 to 2.5. The alloy has an alloy phase which is substantially a Laves phase of an intermetallic compound of A and B, and has a crystal structure of a hexagonally symmetric C14 type having crystal lattice constants, a and c, of from 4.8 to 5.2 angstroms and from 7.9 to 8.3 angstroms, respectively, and/or a cubically symmetric C15 type having a crystal lattice constant of from 6.92 to 7.70 angstroms. A method for making the electrode is also described using a sintering or non-sintering process.
