Summary

A novel glass-mica composite seal was developed based on a previous concept of “infiltrated” mica seals for solid oxide fuel cells. A Ba-Al-Ca silicate sealing glass was mixed with mica flakes to form the glass-mica composite seals. The glass-mica composite seals were tested for thermal cycle stability in terms of the high temperature leakage under applied compressive stresses. Post mortem analyses were used to characterize the fracture and leak path of the glass-mica composite seals.
