- Abstract
The perovskite cathode material of SrFe0.9Sb0.1O3- (SFS) was prepared by glycine-nitrate process (GNP). The SFS oxides sintered at 1150,1200 and 1250 §C for 10 h were crystallized into a single phase perovskite structure, respectively. The effect of sintering temperature on crystal structure, conductivity and polarization resistance was also discussed in detail. The X-ray diffraction and SEM results show that the density increases with the increase of sintering temperature. The results of electrical properties show that the conductivity of SFS samples is dominated by p-type conductivity, and the conduction behavior is in accordance with the mechanism of small polaron jumping. With the rising sintering temperature, the conductivity of prepared samples increases gradually. In the temperature 650 800 §C, the conductivity values are 57.8 32.5, 63.6 35.8 and 74.5 40.3 S cm1 for the SFS samples of sintering at 1150, 1200 and 1250 §C, respectively. The SFS cathode has a good chemical compatibility with the SDC electrolyte at temperatures below 950 øC. The polarization resistances of SFS cathode were 0.064, 0.052 and 0.047 cm2 at 800 §C, respectively. The results show that the SFS material of sintering at 1250 øC has promising prospects for the application of IT-SOFCs.
