Summary

The formation of secondary phases at the interface between zirconia electrolytes and Sr-doped Lanthanum Manganite in planar Solid Oxide Fuel Cells (SOFCs) was investigated. 8 mol% Yttria-Stabilized Zirconia (YSZ) electrolyte was fabricated by tape casting and coated with the cathode material La0.65Sr0.30MnO3 (LSM) by screen-printing. The structures were co-fired under different conditions. The sintered specimens were annealed at 1000d̀C for various periods. The formation of secondary phases and interdiffusion effects at the interface of these samples were studied by X-ray diffractometry (XRD), scanning and transmission electron microscopy equipped with energy-dispersive spectroscopy (SEM- and TEM-EDS). The results of the formation of secondary phases and diffusion effects are discussed with regard to the processing conditions.
