Abstract

In this report, the optimized rated power output and the optimized hot water tank capacity of SOFC in accordance with the energy demand of collective housing are clarified. And authors proposed "the bathtub heat storage operation" and clarified its efficiency. The conclusions are as follows. 1. The optimized rated power output related with the total annual demand of electric power and hot water supply. The optimized hot water tank capacity related with the heat-to-power ratio of demand. 2. "The bathtub heat storage operation" was effective in the cases where the hot water tank capacity was less than 30L. It shows that it was possible to make the hot water tank for collective housing smaller without greatly lowering the energy saving efficiency of SOFC.
