Notes:
A concept for quantitative design of sealing glasses was proposed for planar solid oxide fuelcells (SOFC) applications, by which chemical and physical compatibility of a glass with other materialscan be predicted through simulation based on a thermodynamic model and a combined model. Using thismethod, a sealing glass was successfully developed. The thermal expansion coefficient (TEC) of the glasswas determined to be 9.9×10-6 K-1 (room temperature to 631°C), which is very close to the value of 10.0 ×10-6 K-1 measured for 8YSZ. Investigations revealed that the sealing glass had very good thermal stability,where the change of the TEC value was within the range of equipment error. The glass was also proved tobe chemically compatible with 8YSZ, by the fact that no obvious interfacial reaction was detected afterbeing heat-treated with 8YSZ at 700°C for 500 h
