Synthesis of nano-sized gadolinia doped ceria powder by aerosol flame deposition

Abstract

In this work. aerosol flame deposition method was applied to deposit spherical and dense gadolinia-doped ceria (GDC) particles in the sub-micron range for the electrolyte application in solid oxide fuel cell. The particle size distribution was dependent on processing parameters such as the concentration of the precursor solution, the hydrogen gas flow rate, the oxygen gas flow rate, and flame conditions. GDC electrolyte thin layer was also fabricated from the liquid Source materials by AFD method. Microstructure of synthesized powder was characterized using XRD and SEM.
