| Outline of Final Research Achievements |
Metal hydride(MH) is candidate for hydrogen compressor because its equilibrium pressures obeys van’t Hoff equation; thus the pressure increases exponentially with the increase in temperature. Hydrogen fueling station, where hydrogen is stored in the liquid state (T= 23.6K), can also be considered as a large cold energy source. Using this cold energy, we tried to obtain compressed hydrogen for hydrogen cylinder (20MPa) and FCV (70MPa) by the MH hydrogen compressor(MHHC).
AB2-type Ti-based Laves alloys were selected for the MHHC because their equilibrium pressure could be tunable by their compositions and their pressure hysteresis is small. A high hydrogen pressure experimental facility was constructed at AIST/FREA, then, hydrogen ab/desorption properties at high pressure (up to 100MPa) were measurable. With the aid of this facility, it was found that a favorable hydrogen compression ability of Ti(CrMnFe)2 alloy was obtained by increasing temperature up to 305K for hydrogen cylinder.
