| 摘要 |
<p>A hydrogen storing alloy comprising a body-centered cubic lattice structure having a composition of MgXaVb wherein "a" and "b" are such that 0.2</=a</=5 and 0.2</=b</=5 are satisfied, and "X" is one or more metals selected from a group consisting of Cr, Mn, Fe, Co, Cu and Ni. Since the body-centered cubic lattice structure is under the non-equilibrium state in which the bonding strength between the stored hydrogen and the alloy is relatively weak, the hydrogen absorption and release at the ordinary temperature level are possible. The conventional magnesium-based hydrogen storing alloy is sufficient in its higher hydrogen storing amount and lightness. However, the conventional alloy could not absorb and release at the ordinary temperature level, thereby inhibiting the commercial availability. The present invention can provide the magnesium-based hydrogen storing alloy which can absorb and release the hydrogen at the ordinary temperature level. <IMAGE></p> |
