Title: Thermal Cycle Stability of a Novel Glass-Mica Composite Seal for Solid Oxide Fuel Cells: Effect of Glass Volume Fraction and Stresses

Abstract

A novel glass-mica composite seal was developed based on a previously of ''infiltrated'' mica seals for solid oxide fuel cells. Ba-Al-Ca silicate sealing glass-mica composite seals. The seals were leak tested for short-term thermal cyfunction of glass volume fraction. Composite seals with 10 v% and 20 v% glatested under compressive stresses from 3 psi to 100 psi and voltage tests on dense 8YSZ electrolyte with the glas-mica composite seal showed very good thermal cycle stability.
