Summary

Planar solid oxide fuel cells require a seal to separate air and fuel and to bond components together. the development of seals with acceptable lifetime and performance has proven to be technically challenging. in this paper, a novel method to form durable seals that meet the requirements for commercial application will be described. the seal material is a composite with a preceramic polymer-derived matrix and particulate fillers. Partial pyrolysis is used to control shrinkage during pyrolysis of the seal material. Fillers are selected to adjust the seal material's physical properties. Seal compliance, and its effect on stack stresses, will also be discussed.
