STAINLESS TI-FE BASE ALLOY FOR HYDROGEN STORAGE

摘要

A titanium-iron-type alloy for the storage of hydrogen having an atomic composition corresponding to the formula TiwFExM'yM"z in which M' is a metal selected from the group consisting of chromium and vanadium and having an ability to render a titanium-iron based alloy substantially nonoxidizable in the presence of oxidizing impurites in the hydrogen to be stored; M" is a metal selected from the group consisting of nickel and manganese but is nickel where M' is chromium and is capable of promoting absorption of hydrogen in the alloy; and y and z are each between 0.01 and 0.2; w, representing the atomic concentration of titanium is at least equal to the sum x + y + z. The alloy can be charged with hydrogen, stored and desorbed from hydrogen.
