The heat transfer characteristics of the chemical thermal storage system based on decomposition reactions of the inorganic hydroxides Mg(OH)//2 and Ca(OH)//2 are carried out numerically and experimentally to investigate the configuration effects on storage performance. Experimental results show that the change in the temperature distribution and interface location of a fin-equipped packed bed can be validly simulated by a numerical model. In addition, the suitable configuration for high performance storage is found to be 0. 4-0. 6 cal/cm**2 - sec of power input, 0. 03-0. 04 cm of fin thickness, 0. 05-0. 1 cm of bottom plate thickness, 20-30 cm**3/cm of packed capacity, and the ratio of fin height to interval up to 10-12.
