Osaka Gas Co., Ltd. and Kyocera Corporation have developed 1kW class solid oxide fuel cell (SOFC) cogeneration system. We installed SOFC residential cogeneration system in a house, living a family of four. From the end of November 2005 to the beginning of March 2006, total 2000 hours, we carried out the first trial operations for actual home use of SOFC residential cogeneration system. SOFC system showed high net ac efficiency under the condition of following the electric load of the actual house. At rated power, ac 1kW, net ac efficiency and hot water heat recovery efficiency were 49% (LHV) and 34% (LHV), respectively. The mean net ac efficiency of each days, that is total efficiency of 24 hours, ranged 42-48% (LHV), when the mean net ac power of SOFC were 480-680W.
