New presentation method for pulverization behavior of the hydrogen storage alloys

Abstract

The hydrogen storage alloys are expected as useful smart materials such as hydrogen storage alloys for fuel cells, battery electrodes and materials for other energy related systems. The H₂ storage alloys are usually pulverized at each sorption cycles by the large volume expansion. In investigating the effect of alkaline pretreatment on pulverization, we examined the new presentation methods for the powder distribution in the course of H₂ sorption cycles.
