摘要：
Deposition of dense 8 mol% Y2O3-stabilized ZrO2 (YSZ) electrolyte thin-films with and without Ce0.9Gd0.1O1.95 (CGO) interlayer by spin coating of polymeric precursor solutions on a porous La0.6Sr0.4Co0.2 Fe0.8O3 (LSCF) substrate and the electrical properties of the constructed thin-film cell were investigated. Anisotropic crystal growth in the YSZ thin films annealed at 1150degreesC was confirmed by XRD and SEM. The high-temperature chemical reaction between YSZ and LSCF was depressed by coating a CGO interlayer on the porous LSCF substrate before coating YSZ thin film. The impedance measurements of the electrochemical cell constructed by the LSCF electrode-supported YSZ thin-film electrolyte with CGO interlayer showed a lower electrode reaction resistance.
