ABSTRACT:
An economical metallic material for storage of hydrogen comprising an alloy representable by the formula AB.alpha. in which "A" comprises from 50 to under 100 atomic percent of titanium and the remainder which is at least one element selected from the group I consisting of zirconium and hafnium, B comprises from 30 to below 100 atomic percent of manganese and the remainder which is at least one element selected from the group II consisting of chromium, vanadium, niobium, tantalum, molybdenum, iron, cobalt, nickel, copper and rare earth elements, and .alpha. is a value indicating a ratio of B to A, and is in the range of 1.0 to 3.0.
The materials of the invention very easily absorb large amounts of hydrogen and efficiently release it at other predetermined temperatures, pressures and electrochemical conditions, whereby it is able to store hydrogen safely, usefully and economically.
