HYDROGEN STORAGE MATERIALS HAVING EXCELLENT KINETICS, CAPACITY, AND CYCLE STABILITY

摘要

A BCC phase hydrogen storage alloy capable of storing approximately 4.0 wt.% hydrogen and delivering reversibly up to 3.0 wt.% hydrogen at temperatures u p to 110~C. The hydrogen storage alloys also possess excellent kinetics whereb y up to 80% of the hydrogen storage capacity of the hydrogen storage alloy may be reached in 30 seconds and 80% of the total hydrogen storage capacity may be desorbed from the hydrogen storage alloy in 90 seconds. The hydrogen storage alloys also have excellent stability which provides for long cycle life.
