The CaO-SiO2-B2O3-Al2O3-La2O3 sealants with different alumina contents were fabricated by high-temperature melting method for intermediate temperature solid oxide fuel cell (ITSOFC). The glass transition temperature (Tg) and crystal temperature (Ts) of the sealant with different alumina content was characterized by TG-DSC. And the composition phase of the sealant was detected by XRD. The resistivity of sealant tested by electrochemical workstation was higher than 22 kΩ·cm2, which met the requirement for ITSOFC. Through the detecting of the wetting angle, the adhesion of sealant and anode materials was very good, and the single cell sealed with alumina tube successfully.

CaO-SiO2-B2O3-Al2O3-La2O3 system sealants with different B/Si ratios of 0.38~0.82 were prepared by high-temperature melting method for intermediate temperature solid oxide fuel cell (ITSOFC). The glass transition temperature (Tg) and softening temperature (Ts) of the sealant were analyzed by TG-DSC. The complex phases of the sealants detected by XRD were consistent with the calculation results generally. The resistivity of the sealants tested by electrochemical workstation was above 65 kΩ·cm2, and the wetting angle was also calculated. The prepared sealants basically meet the sealing requirement for ITSOFC.
