Hydrogen storage alloy


An alloy able to dissolve large quantities of hydrogen between crystal lattices.

Hydrogen storage alloys are used to store hydrogen gas. These alloys include La-Ni5, Mm-Ni5 (Mm is misch metal, a mixture of cerium group rare earth metals), Ti-Fe, Ti-Mn, Li-Fe, and Mg-Ni. This alloy can be used as an actuator by varying the temperature. At a rise in temperature, this alloy desorbs hydrogen gas and at a drop in temperature absorbs the gas. This is also promising as an energy storage material.
