Mitsubishi Materials Corporation, The Kansai Electric Power Co., Inc., and Kyushu University have been working together on multiple projects for developing intermediate-temperature SOFCs. Substantial technical advancement has been made in manufacturing SOFC units ranging from a 1 -kW class module to a scalable 10-kW class combined heat and power (CHP) system. The core technology is based on high-performance cells operable in a temperature window between 600° and 800°C. 

While demonstrating the 10-kW class module capability in meeting the DC target specifications, a combined heat and power (CHP) system is developed for utilizing the module within a complete system configuration [19, 20]. The photograph shown in Fig. 9.14 is for the actual 10-kW class CHP system installed at Rokko Testing facilities of The Kansai Electric Power Co., Inc. The system consists of a 10-kW class SOFC module, a unit for gas and water supply equipment, a unit for power electronics, a control unit, and an exhaust heat recovery unit. 

An alternative approach to reduce the operating temperature is to use new electrolyte materials such as scandium doped zirconia (SeSZ), and rare earth doped ceria (RDC) which have the fluorite type stmeture, or lanthanum gallate based oxides such as (La,Sr)(Ga,Mg)03 (LSGM) with perovskite stmeture, all of which have higher ionic conductivities than YSZ. An 1 kW class SOFC stack with (La,Sr)(Ga,Mg,Co)03 electrolyte was demonstrated by the collaboration of Mitsubishi Materials Corp. and The Kansai Electric Power Co., Inc. in 2001,...
