Quick-Start-Up Type SOFC Using LaGaO3-Based New Electrolyte
TOTO is the top sanitary ware manufacturer in Japan. The company also has much experience in making both traditional and advanced ceramic products. Solid oxide fuel cells (SOFCs) are mainly composed of ceramics, and our fabrication technology has been utilized to produce high-performance SOFCs at a low cost. TOTO commenced research and development of the tubular-type cell (whose diameter is 16 mm) using a zirconia-based electrolyte for stationary power applications in 1989 (Table 10.1). We have demonstrated more than 10,000 h of continuous operation in single-cell tests, and our modules have accumulated more than 3,000 h of operation as of 2004 with electrical efficiency (Lowe heating value, LHV) of 55% . Since 2004, TOTO has been collaborating with Hitachi, Ltd. on a new NEDO (New Energy and Industrial Technology Development Organization) project. We are developing a 20-kW class co-generation system by integration with TOTO’s stacks (Fig. 10.1). Meanwhile, TOTO also started developing micro-tubular SOFCs using an LaGaO3-based new electrolyte for portable power applications in 2002.
