Popis:	In this work, the Aerosol Flame Pyrolysis Deposition (AFPD) technique was applied to deposit yttria-stabilized zirconia powder from the liquid source materials in order to prepare film type electrolyte for SOFC. The spherical and dense yttria-stabilized zirconia particles were synthesized in the submicron range and the particle size distribution was dependent on the concentration of the precursor solution and flame conditions. The spherical and dense solid YSZ particles were synthesized and the XRD results revealed that the crystallinity of particles were already excellent without additional heat treatment. Mean diameters of the particles were approximately 400–600 nm and the particles were polycrystalline composed of approximately 20-nm-sized grains. YSZ electrolyte thin layer was also fabricated from the liquid source materials by AFPD method.
