Description
The subproject “Development of a MIC-cell sealing” is part of
the collaborative FERMI project of different partners from industry
(Hexis) and universities (ZHAW IMPE and ICP, FHNW). The project is
supported by founding from Swiss federal office of energy SFOE.
The laboratory of ceramic materials develops glass ceramic based
sealings for the separation of reaction zones in between a SOFC
high temperature solid oxide fuel cell. Besides the separation
effect, the sealing should suppress unwanted reactions between
cathode and ceramic zirconia electrolyte. Such reactions lead to a
transformation zone where new compounds are formed. Additionally,
such reactions impede the use of thinner electrolytes with lower
electrical resistivities. The reaction between the metallic
interconnector as additional sealing interface partner with some
compounds of the glass ceramics furthermore influences the
integrity of the sealing.
