Abstract
Abstract A method of producing a vanadium-based metal hydride which comprises reacting hydrogen gas at a temperature between about 0 DEG and 100 DEG C. with a vanadium-based binary solid solution alloy having a body-centered cubic structure and having a formula V1-xMx, wherein M is a metal selected from the group consisting of manganese, chromium, cobalt, iron, nickel and mixtures thereof and wherein x varies from at least about 2 atom percent up to the solubility limit of cobalt, iron and nickel and up to about 20 mol % of manganese and up to about 40 mol % of chromium in said solid solution alloy is disclosed.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
170 words
A method of producing a vanadium-based metal hydride which comprises reacting hydrogen gas at a temperature between about 0° C. and 100° C. with a vanadium-based binary solid solution alloy having a body-centered cubic structure and having a formula V 1-x M x , wherein M is a metal selected from the group consisting of manganese, chromium, cobalt, iron, nickel and mixtures thereof and wherein x varies from at least about 2 atom percent up to the solubility limit of cobalt, iron, nickel and up to about 20 mol percent of manganese and up to about 40 mol percent of chromium in said solid solution alloy; Wherein the reaction rate of said solid solution alloy with hydrogen at said temperature is at least about 100 times the reaction rate of un-alloyed vanadium with hydrogen at said temperature and identical hydrogen pressures and wherein the reacting of said solid solution alloy with hydrogen at said temperature is effected without preactivation of said solid solution alloy with hydrogen at a elevated temperature.
Claim 2
Independent Claim
170 words
A method of producing a vanadium-based metal hydride which comprises reacting hydrogen gas at a temperature between about 0° C. and 100° C. with a vanadium-based binary solid solution alloy having a body-centered cubic structure and having a formula V 1-x M x , wherein M is a metal selected from the group consisting of manganese, chromium, cobalt, iron, nickel and mixtures thereof and wherein x varies from at least about 2 atom percent up to the solubility limit of cobalt, iron, nickel and up to about 20 mol percent of manganese and up to about 40 mol percent of chromium in said solid solution alloy; Wherein the reaction rate of said solid solution alloy with hydrogen at said temperature is at least about 100 times the reaction rate of un-alloyed vanadium with hydrogen at said temperature and identical hydrogen pressures and wherein the reacting of said solid solution alloy with hydrogen at said temperature is effected without preactivation of said solid solution alloy with hydrogen at a elevated temperature.
