Abstract: Since 2002, TOTO Ltd. has been developing anode support type microtubular cell stack modules that work at lower temperatures as power generating systems with capacities ranging from tens to hundreds of watts. Using lanthanum gallate thin film electrolyte, we have successfully developed a cell stack that is capable of generating power at temperatures of 500°C-700°C. This cell stack has been confirmed to have high tolerance against rapid thermal shock. TOTO Ltd. and Noritz Corp. have been jointly developing 700W residential SOFC cogeneration system. Since 2008, we have taken part in the “Demonstrative Research on Solid Oxide Fuel Cells Project” conducted by New Energy Foundation(NEF) and New Energy and Industrial Technology Development Organization(NEDO). We had installed 2 units in 2008 and 6 units in 2009. In this paper, the development statuses of SOFC system and demonstration result are reported.
