Abstract

(1-xwt%) La_0.6PrSr_0.4NiO₄ - (xwt%) Ce_0.8Pr_0.2O₂ (x = 0, 10, 20, 30, 40, 50), abbreviated as LPSN-xCPO, were prepared and used as composite cathode for intermediate temperature solid oxide fuel cell (IT-SOFC). XRD result suggested that no chemical reaction occurred between LPSN and CPO after sintering at 1200 °C for 4 h. Electrical conductivity of LPSN-xCPO decreased with x. LPSN-40CPO exhibited the best performance on cathode impedance spectra under open-circuit condition. At 700 °C, Exchange current density of LPSN-40CPO and LPSN was 50.1 and 15.8 mA cm^-2, respectively, and the polarization resistance R_P of LPSN-40CPO was 0.22 Ω cm², which is about one-eighth of that of LPSN. The OCV of the cell with LPSN-40CPO as cathode was about 0.78 V, and the maximum of power density was about 88 mW cm^-2. LPSN-40CPO can be a promise candidate for cathode in IT-SOFC.
