Glass Mica Composite Seals for Solid Oxide Fuel Cells

Conference ·
OSTI ID:889088

A novel glass-mica composite seal was developed based on the 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 thermal cycle stability in terms of the high temperature leakage and compressive stresses. Post mortem analyses were used to characterize the fracture and leak path of the glass-mica composite seals.
