The Kansai Electric Power Co., Inc. (KEPCO) and Mitsubishi Materials Corporation (MMC) have been undertaking joint study of intermediate temperature solid oxide fuel cell (IT-SOFC), which can operate at between 600 and 800℃. IT SOFC of KEPCO and MMC is characterized by metallic separators, seal-less structure for the stack, flexible arm structure for the separators and highly conductive lanthanum gallate-based oxide for the electrolyte. The development of 10 kW-class CHP (Combined Heat and Power) system under a project supported by New Energy and Industrial Technology Development Organization (NEDO) was started in FY2004. In FY2007, the 10 kW-class CHP system gave the electrical efficiency of 41% HHV on AC output of 10 kW and the overall efficiency of 82% HHV when exhaust heat was recovered as 60℃ hot water. And two long-term field tests for 3,000 hours were carried out in FY2007 and 2008.
