Synthesis, Forming and Characterization of Ceramic Materials for the Planar Solid Oxide Fuel Cell (SOFC)

Chemically-homogeneous and well-characterized ceramic powders have been used for the preparation and investigation of the SOFC components. The powders were synthesized by spray drying and subsequent calcination. The resulting powders were characterized with regard to the crystalline phases, chemical analysis, specific surface area, particle size and particle size distribution, morphology and particle agglomerates. These parameters are very important for forming thin, flat ceramic sheets and components by tape-casting and screen-printing technology. Forming process, sintering, electrical conductivity and compatibility are discussed.
