A variety of seals such metal-metal, ceramic-metal and ceramic-ceramic are needed for solid oxide fuel cells to enhance reliability and life of the cell stacks. These seals are expected to function in the most severe environments of a SOFC operating between 600-900°C and under thermal gradients. An overview of the requirements, type of possible seals, approaches for reliable seals, and recent results on ceramic-metal seals will be presented.
