Criteria for the Sealants

The stack assembly procedure also affects the seal selection process. For instance, a laminate structure of anode, electrolytes, and cathode is formed by the plasma spraying technique. The microstructuring processing steps must be controlled so that the interfacial reactions and interdiffusion between those layers can 

Matching CTE with tha adjoining component Thermal cycling degradation resistant 

Ability to withstand pressure Non-locallsed leak rate Acceptable load frame design 

Three seals are used for the cell-to-frame design
