Ba0.08Y0.04Co2.5Fe0.09O.4-6cathode deposited on GDCio electrolyte by spray pyrolysis technique
The properties of a thin-film cathodc BYCF (Bail osYo <>4Co:.5Fe<) 09C>4-is) layer prepared by spray pyrolysis between dense electrolyte (GDCio) pellets were studied. This paper presents the method for depositing the cathode material on the electrolyte, as well as its niicrostructure, electrical conductivity and AC impedance characteristics. The results showed that a layer with 20 (xm thickness and high porosity was obtained using the spray pyrolysis technique. The niicrostructure showed excellent adherence on the electrolyte. The electrical conductivity and AC impedance measurements indicated these properties are a good candidate for cathode material with spray pyrolysis.
