Summary

A critical technical challenge to the introduction of solid oxide fuel cells (SOFC) in commercial markets is the need for a durable sealing material that can be manufactured cost effectively and deliver the required performance. In addition there is a need for improved SOFC seals to enable the use of SOFC's in gas-turbine combined cycle applications. The seal material must be able to bond to all materials in a fuel cell and act as a barrier to air and fuel over the operational lifetime of the SOFC device. This paper will describe recent studies on the use of amorphous, non-oxide materials derived from preceramic polymers for use as sealing materials. Critical issues, material properties, and results of initial evaluations will be described.
