Compliant alkali silicate sealing glass for solid oxide fuel cell applications: Combined stability in isothermal ageing and thermal cycling with YSZ coated ferritic stainless steels

► This work is a continuation of a novel SOFC glass seal based on glass which does not readily crystallize into glass-ceramics. ► The findings from this work on combined ageing and cycling are as follows. ► The compliant glass is isothermally stable in dual environment. ► The compliant glass is chemical compatible with YSZ electrolyte and coating. ► The glass did show some crystallization over 1000 h ageing.
