Abstract

Make the composite electrolyte by doping Al2O3 powders ,in the ratios of 1:0.02 and 1:0.04 respectively to the electrolyte masses, into initial powders of the electrolyte-BaZrCeYO made in the method of Pechini. After 10 hours sintered at 1400 , the composite electrolyte was completed , XRD test carried out, respectively in the range of 500-800 , Ac impedance spectrum tested, and adopted the composite electrolyte impedance test and output characteristic. The results showed that: Al element in the calcinations process replaced B atoms of ABO3 perovskite structure into the crystal lattice; electrolyte impedance and cell impedance increased significantly when the doping of Al2O3 increased, and the output characteristic performance of single cell was significantly reduced.
