Glass and glass-ceramic materials were investigated as SOFC seals at 800 ～ 850 ℃. The material was based on the glass and glass-ceramic in the BaO-CaO-Al2O3-SiO2-La2O3-B2O3 system. The sealant has a minimum thermal expansion mismatch with yttria-stabilized zirconia (YSZ)electrolyte and Ni/gYSZ for the anode. The sealant has a superior stability during the process of operation in SOFC and can withstand thermal shock during the process of thermal cycling. The results show that the BaO-CaO-Al2O3-SiO2-La2O3-B2O3 system sealant can be used as sealing materials for SOFC.
