Hydrogen Storage by Hydrogen-Absorbing Alloys

Abstract

Metal hydrides which reversibly absorb and desorb hydrogen at ambient temperature and moderate pressure, so-called “hydrogen-absorbing alloys”, and their application to hydrogen storage systems have been extensively studied since the early 1970s. Under rising concerns about energy and environment problems, the research and development of this technological field has been intensified, especially toward the effective utilization for fuel cell vehicles. This paper briefly gives a personal review of hydrogen storage technologies using meta hydrides and other media.
