Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
165 words
A C15 type alloy hydrogen storage electrode which comprises a body of an alloy of the general formula, AB a , or a hydride thereof, in which A represents Zr or a mixture of at least 30 atomic percent of Zr and the balance of at least one element selected from the group consisting of Ti, Hf, Al and Si, B represents Ni and at least one element selected from the group consisting of 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, Pr, Nd, Th, Sm and Mm where Mm is a mixture of rare earth element and a is a value of from 1.0 to 2.5, said alloy having an alloy phase which is substantially a Laves phase of an intermetallic compound A and B and having a crystal structure of a cubically symmetric C15 type having a crystal lattice constant of from 0.692 to 0.770 nm.
Claim 2
Dependent Claim
