Abstract

A metal hydride heat pump system has a plurality of operating units, the metal hydride heat exchange medium of each operating unit be a combination of a first metal hydride having a lower equilibrium dissociation pressure at the operating temperature and a second metal hydride having a higher equilibrium dissociation pressure at the operating temperature and the metal hydrides being such that hydrogen can flow freely between the two metal hydrides, wherein the equilibrium dissociation pressure characteristics of one or both of the first and second metal hydrides in a given operating unit differ from those of one or both of the first and second metal hydrides in at least one other operating unit.
