Solid oxide cells (SOCs) devices are of great interest for effective power generation and for highly efficient conversion of electricity to hydrogen, fuels and chemicals using high temperature electrolysis. Durable SOCs can be achieved only by a reliable integration and joining technology. In this context, glass-based materials, with multiple functional compositions and properties play a key role in the final performance and durability. In SOC stack designs the metallic interconnect must be sealed both to the interconnect frame, thus presenting significant challenges, even considering the high operating temperatures (800-1000°C). Strong efforts are being directed towards the development of lower temperature SOC, operating between 600 and 700°C.
