Structural and Electrochemical Properties of Pr1−xSrxCoO3−δ as a Cathode Material for Intermediate Temperature-Operating Solid Oxide Fuel Cell

摘要: Reducing operation temperature of Solid Oxide Fuel Cell (SOFC) may provide many advantages for material selections sealing, interconnects and Balance-Of-Plant (BOP). This study focus on the advanced performance another cathode according to structure change about Pr1−x Srx CoO3−δ compositions (PSCs, x = 0, 0.3, 0.5 0.7). High XRD measurement electrochemical impedance methods were used characteristics as a Intermediate Temperature-operating (IT-SOFC) application. Lattice parameters crystal structures PSCs well Area Specific Resistance (ASR) solid oxide electrolytes are discussed at various values (x 0.7) temperatures. One PSC showed 0.17 Ωcm2 ASR 10% Gd-doped cerium 700°C.Copyright © 2006 by ASME
