LaNi₅水素吸蔵合金の水素吸収特性に及ぼす水処理の影響

抄録

The hydrogen storage alloy is an important element in hydrogen system as energy carrier. Unfortunately by contacting with air the hydrogen storage alloy becomes to be deactivated and usually does not absorb any hydrogen more. Recently we found the effect of alkaline treatment and subsequent water rinsing process on the H₂ sorption characteristics, where the H₂ sorption is improved even after a significant oxidation. In this study we investigated the effect of only by the treatment at the water treatment on the H₂ sorption characteristics. We found the preferred effect only at adequate temperature and with treatment duration.
