Heat exchange apparatus with use of hydrogen storing material

Abstract

A regenerative heat exchange apparatus for use with a hydrogen storing material is presented. The apparatus includes a regenerator chamber packed with a heat storing material, and the regenerator chamber is disposed in between a high temperature fluid pathway and a low temperature fluid pathway of a heat exchanger. The high temperature fluid pathway is connected to a heat source and the low temperature fluid pathway is connected to a heat utilizing system. The regenerator chamber is connected via a pressure controlling mechanism to a hydrogen reservoir. Excess heat of the high temperature fluid can be stored by a decomposition reaction (endothermic reaction) of the hydrogen storing material to discharge hydrogen, and a deficiency in the quantity of heat required for the low temperature fluid can be supplemented by a hydrogenation reaction (exothermic reaction) of the hydrogen storing material to absorb the discharged hydrogen.
