摘要
The (1-x)BaZr0.9Y0.1O3-δ(BZY)-xCe0.8Sm0.2O2-δ(SDC, x =0.1,0.3,0.5 and 0.7) composite electrolytes were prepared by combining a gel polymerization method with a ball milling. X-ray diffraction (XRD) patterns show the mixture of BZY and SDC is only crystalline phase as the composite electrolyte. The relative density,grain size and total conductivity of composite electrolytes increase significantly with the increase of SDC content. The maximum conductivity of 0.1 BZY-0.9 SDC reaches 2×10^2 S·cm^-1 at 600 ℃ in wet air,which is close to the conductivity of SDC.
