Article Preview

La0.9Sr0.1Ga0.8Mg0.2O2.85 (LSGM) electrolyte films were successfully prepared by slurry spin coating method on porous La0.7Sr0.3Cr0.5Mn0.5O2.75 (LSCM) anode substrates. Ethyl celluloses content, coating cycles for slurry spin coating on the fabrication LSGM electrolyte films were investigated. The compatibility between LSGM and LSCM powders, microstructures and electricity conductivity of fabricated LSGM films were examined using XRD, SEM and electrochemical workstation. The film with good apparent morphology and electrical conductivity were obtained when the operating parameters were setted as the content of ethyl cellulose 10wt%, and the coating cycles 5.
