Abstract
A heat pump device comprising a closed receptacle divided into a first chamber and a second chamber, means forming a hydrogen flow passage extending through the two chambers, said hydrogen flow passage permitting the flow of hydrogen but rejecting the flow of metal hydrides between the two chambers and being made at least partly of a porous material permeable to hydrogen and elastically deformable in response to an applied pressure, a first metal hydride filled in the first chamber and a second metal hydride filled in the second chamber.
