Abstract
⺠The Pr1 â xSrxCoO3 â δ perovskite-type oxides (x = 0.1, 0.3, 0.5, and 0.7) are synthesized by the Pechini and glycine-nitrate-process (GNP) method and investigated the effect of Sr substitution for Pr. ⺠The microstructures of Pr1 â xSrxCoO3 â δ are identified by X-ray powder diffraction (XRD) and field emission scanning electron microscopy (SEM). ⺠The temperature dependence of electrical conductivity with Pr1 â xSrxCoO3 â δ is evaluated by 4-probe method. The electrical conductivities and redox properties of Pr1 â xSrxCoO3 â δ are measured simultaneously under a wide p(O2) range at 973 K. ⺠The electrochemical performance of Pr1 â xSrxCoO3 â δ single cell is measured by Ni-GDC anode-supported cell.
