Abstract

This invention relates to a method for manufacturing a heat transfer module to improve the thermal efficiency of a hydrogen adsorption alloy. The hydrogen absorption alloy particles are coated with a metal which is different from that of the alloy, followed by the formation of a compact with the coated particles. The compact so formed has a substantially uniform specific gravity. The compact is then inserted in a pipe mode of a metal which is different from that of the alloy. The pipe has an internal diameter which is a function of the diameter of the compact and the free expansion coefficient of the compact. The method will improve the usefulness of hydrogen adsorption alloy in practical use.
