For a reliable and safe operation of Solid Oxide Fuel Cells (SOFCs), gastight sealings with high long-term stability are required. Due to stringent demands to the sealing materials resulting from working temperatures up to 900 °C, harsh atmospheres and the need of electrical insulation, only few materials are suitable for this application. Among the different sealing concepts, still the most common used is to apply sealings with glasses or glass ceramics. Glass sealings are related to rigid joints forming chemical bonds with joined components. Therefor the thermo-physical properties of sealing material have to be adapted to these materials. This was realized by a glass forming system of BaO-SiO2-Al2O3 with additional oxides for controlling ...
