Abstract

LaxSr1-xCoyFe1-yO3 (LSCF) perovskite oxides have been successfully synthesized by GNP method (Glycine Nitrate Process) to use as a CATHODE ELECTRODE in solid oxide fuel cells. X-ray diffraction (XRD) results showed formation of single phase LSCF powder without presence of any impurity. In this study, LSCF and LSCF/GDC inks were used as cathode material. The inks were analyzed with an in-situ sintering study where the in-plane conductivity was used to investigate the eﬀect of diﬀerent sintering temperatures on the conductivity of the electrodes. Compared to LSCF cathode, it was shown that LSCF/GDC has lower in-plane conductivity due to the present of GDC, which is not an electronic conductor at high temperature. Electrochemical analysis was performed at different temperatures to deeply understand the behavior of the cathode materials. A two-electrode configuration was used to measure the IMPEDANCE of the cells. LSCF/GDC cathode manifest good performances with polarization resistance of 0.027 Wcm2 at 750°C in the air atmosphere.
