AB Ce0.9Gd0.1O1.95 (CGO) protective layers are prepared by two different methods to prevent the reaction betweenthe Zr0.84Y0.16O1.92 (YSZ) electrolyte and the La0.6Sr0.4Co0.2Fe0.8O3-δ (LSCF) cathode. In the first method, theCGO layers are deposited by an airbrushing technique from an ink containing CGO particles without and withcobalt as sintering aids. The second strategy consists in preparing both a dense CGO barrier layer and a porousLSCF cathode by spray-pyrolysis deposition, in order to further reduce the fabrication temperature and minimizethe reaction between the cell components. The samples prepared by spray-pyrolysis exhibit better performanceand durability than those obtained by conventional sintering methods. The results suggest that the interfacialreactivity between YSZ and LSCF as well as the Sr-enrichment at the cathode surface can be avoided by usinglow-temperature fabrication methods and by operating at temperatures lower than 650 °C.
