CHEMICAL HEAT STORAGE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a chemical heat storage device capable of preventing decline in a reaction rate of a chemical thermal storage medium when used repeatedly. SOLUTION: The chemical heat storage device is constituted so that (1) the chemical heat storage device includes a heat storage body having the chemical thermal storage medium absorbing/generating heat by dehydration-hydration reaction and a heat transfer body made of a heat transfer material to give/receive heat to/from the chemical thermal storage medium and (2) the heat transfer body includes a hydroxyl group or oxide film on a face coming into contact with the chemical thermal storage medium. The heat storage body is a formed body or porous sintered body including the chemical thermal storage medium, and the heat transfer body may be a heat transfer wall coming into contact with the periphery of the formed body or sintered body. The heat storage body may be a composite body including powder of the chemical thermal storage medium and the heat transfer body interposed in the powder of the chemical thermal storage medium.
