| Abstract: | The effects of the Ti/Zr ratio and Mn/Cr ratio on the hydrogen storage properties of Ti-Mn based Laves phase hydrogen storage alloys were investigated. It was found that with the decrease of the ratio of Ti/Zr, the plateau pressure decreases, the hydrogen storage capacity increases slightly and the plateau becomes steeper. With the decrease of the Mn/Cr ratio, the plateau pressure decreases a little, the plateau region becomes shorter, but the hydrogen storage capacity barely varies. The Ti0.85Zr0.15Mn1.6-yCryV0.32Fe0.08(0.1≤y≤0.2) alloys provide promising candidate as a hydrogen source of small-sized fuel cell. |
