Title:
HYDROGEN STORAGE ALLOYS HAVING A LONG CYCLE LIFE
Document Type and Number:
WIPO Patent Application WO2001092592
Kind Code:
A8
Abstract:
A fundamentally new magnesium-based hydrogen storage alloy material which makes it feasible and practical to use solid state storage and delivery of hydrogen to power internal combustion engine or fuel cell vehicles. These alloys have remarkable hydrogen storage capacity of well over 6 weight % coupled with extraordinary absorption kinetics. The alloys also have a dual phase structure (formed by cooling from the melt at a cooling rate of 10<3>-10<4> DEG C) in which an intergranular region thereof provides the alloys with resistance to sintering during high temperature hydriding/dehydriding cycling thereof.
