CHARACTERISTICS OF BaO-Al2O3-B2O3 GLASS SEALANTS FOR LOW TEMPERATURE SOLID OXIDE FUEL CELLS

摘要：

The BaO-Al2O3-B2O3 glasses manufactured for SOFC sealing were studied in this paper. The effect of BaO content on thermal properties and infrared spectra in this system had been discussed. The results show that the trends of crystallization and glass transition temperature increase with BaO content increasing. But a typical property anomaly occurs when BaO content is 35mol％ and its coefficient of thermal expansion has the maximum of the glasses. Thermal properties of some samples are suitable for the sealing of SOFC using Sm doped ceria electrolyte and operating at 400-600℃.
