Research and Characterization of CaO-SiO₂-B₂O₃-Al₂O₃-La₂O₃ Sealant with Different Alumina for ITSOFC

Abstract:

The CaO-SiO₂-B₂O₃-Al₂O₃-La₂O₃sealants 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.
