摘要（英）：

The invention relates to a multielement ferrotitanium hydrogen storage alloy which has a chemical composite: (Ti1-cLc)a(Fe1-x-y-zCrxMyNz)b; in the formula, L is one element of Zr, Hf and Mg, M is one element of Ni, Ta, W, Ce and Cu, N is one element of Nb, V, Zn, Al and B, a is not less than 0.9 and not more than 1.3, b is not less than 0.7 and not more than 1.1, c is not less than 0.005 and not more than 0.2, x is not less than 0.01 and not more than 0.4, y is not less than 0.005 and not more than 0.05, and z is not more than 0.005 and not more than 0.03. The multielement ferrotitanium hydrogen storage alloy can be smelted by a nonconsumable vacuum arc furnace and a vacuum intermediate frequency furnace, and the smelted alloy is easy to activate, has higher hydrogen storage capacity and low cost and is suitable for being used as a fuel cell hydrogen-source alloy.
