研究了 Ti/Zr 比与 Mn/Cr 比变化对 Ti-Mn 基 Laves 相贮氢合金贮氢性能的影响，发现随 Ti/Zr 比降低，合金放氢压降低，贮氢量略微增加，平台坡度变陡；随 Mn/Cr 比降低，合金放氢压降低，平台区变短，但合金的贮氢量变化不大。Ti0.85Zr0.15Mn1.6-yCryV0.32Fe0.08 系列合金当 0.1≤y≤0.2 时比较适宜作为小型燃料电池的氢源。
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.
