Abstract
A reversible hydrogen storage alloy capable of absorbing approximately 4 weight percent hydrogen and desorbing up to 2.8 weight percent hydrogen at temperatures up to 100° C. The hydrogen storage alloy is generally composed of titanium, vanadium, chromium, and manganese. Additional elements such as zirconium, yttrium, iron, nickel, zinc, molybdenum, and tantalum may also be included in the alloy.
