Reducing operation temperature of Solid Oxide Fuel Cell (SOFC) may provide many advantages for material selections of sealing, interconnects and Balance-Of-Plant (BOP). This study focus on the advanced performance of another cathode material and the performance according to structure change about Pr1−xSrxCoO3−δ compositions (PSCs, x = 0, 0.3, 0.5 and 0.7). High temperature XRD measurement and electrochemical impedance methods were used to study the characteristics of the material as a cathode material for Intermediate Temperature-operating Solid Oxide Fuel Cell (IT-SOFC) application. Lattice parameters and crystal structures of PSCs as well as Area Specific Resistance (ASR) of PSCs on solid oxide electrolytes are discussed at various x values (x = 0, 0.3, 0.5 and 0.7) and temperatures. One of various compositions of PSC showed 0.17 Ωcm2 of ASR on 10% Gd-doped cerium oxide at 700°C.
