Web12 jul. 2007 · Hydrogen storage alloys are usually intermetallic compounds consisting of a hydride forming metal component (A) and a nonforming metal component (B) and having specific crystal structures such as C14, B2, D2d, and so on. They absorb and desorb hydrogen reversibly keeping the crystalline state at the moderate temperature. The hydrogen atoms in the crystal lattice lie very nearly along the hydrogen bonds, and in such a way that each water molecule is preserved. This means that each oxygen atom in the lattice has two hydrogens adjacent to it, at about 101 pm along the 275 pm length of the bond. The crystal lattice allows a substantial amount of disorder in the positions of the hydrogen atoms frozen into the structure as it cools to absolute zero. As a result, the crystal structure contains some residua…
