Abstract
Electrolysis of water is an important production method of hydrogen. But it contains much amount of impurities such as O2 and H2O etc. The H2 absorption of hydrogen storage alloy is deteriorated by impurities in H2 gas. Recently, we reported an effect of LiOH and H2O pretreatment, which drastically enhances the H2 absorption of the alloy even after the significant air oxidation. In this paper, we report effect of LiOH pretreatment on H2 absorption of water vapor exposed LaNi5.
