الملخص | Nanocomposite based on LSCF (La0.85Sr0.15Co0.85Fe0.15O3-?) was prepared by a simple chemical precipitation method for application in low-temperature solid oxide fuel cells (LT-SOFC) as a cathode by using basic materials (Rare earth and Transition metal related compounds), sodium hydroxide [as precipitator material] and CTAB [as surfactant]. DTA/TGA of the precursor compound indicated the completion of reaction at about 300 �C. The formation of well-crystalline single-phase perovskite structure with rhombohedral geometry was revealed by the XRD and La-O bond is assigned in the sample revealed by FTIR. SEM analysis unveiled that the sample comprises spherical shaped and homogeneous with an average grain size of about 90�nm. EDAX reveals the elemental composition of the sample. Impedance measurements have been made in voltage ?1.3 volts and the frequency range�42�Hz to 5�KHz. Better conductivity value is attained that may make this system appropriate for application as cathode for Low-temperature solid oxide fuel cells (LT-SOFCs). - 2019, - 2019 Informa UK Limited, trading as Taylor & Francis Group. |
