Abstract
Disclosed is a class of multicomponent, high capacity hydrogen storage materials suitable for use in a heat pump comprising titanium, vanadium, manganese and iron. The hydrogen storage materials are disordered, multiphase, polycrystalline materials which are predominately vanadium and comprise at least a major crystalline phase substantially surrounded by an intergranular phase, with one or more inclusion phases. The materials are characterized by a Bragg x-ray diffraction pattern with a major peak occurring 43 degrees 2 theta. Also disclosed are processes for making the class of materials and a heat pump system utilizing at least one such material.
