摘要

(Pr_0.7Ca_0.3)_0.9MnO_3−δ was synthesized by an EDTA–citrate complexing method. The powder was characterized with X-ray diffraction and transmission electron microscope. The thermal expansion curve and electrical conductivity of (Pr_0.7Ca_0.3)_0.9MnO_3−δ was measured. Electrochemical properties of (Pr_0.7Ca_0.3)_0.9MnO_3−δ cathode with and without SDC impregnation were studied by ac impedance analyzer. The results suggest that (Pr_0.7Ca_0.3)_0.9MnO_3−δ impregnated with SDC is a suitable cathode for IT-SOFCs based on YSZ electrolyte.
