Several glass compositions based on the barium aluminosilicate system have been investigated for their application as sealant for solid oxide fuel cell (SOFC). The developed glasses were characterized through measurement of different properties, viz. coefficient of thermal expansion (CTE), glass transition temperature (T-g), dilatometric softening temperature (T-d), crystallization behavior during prolonged heat-treatment, electrical resistivity measurement, microstructural studies, etc. In addition, bonding behavior between zirconia electrolyte and metallic interconnect in sandwiched condition has also been investigated to find out their suitability as sealant for SOFC. Microstructural investigation revealed a well-adhered bonding between the electrolyte and the metallic interconnect. The optimized glass composition also showed a high resistivity (similar to 10(5) Omega cm) at the SOFC operation temperature (similar to 800 degrees C). (c) 2007 Elsevier Ltd. All rights reserved.
