Ca substituion instead of Sr in La0.58Sr0.4Co0.2Fe0.8O3−δ as a cathode electrode for IT-SOFCs — •Majid Jafari1, Fatemeh Yadollahi Farsani2, Norbert Menzler3, Christian Lenser4, and Fabian Grimm51Plön, Germany — 2Isfahan university of technology, Isfahan, Iran — 3Forschungszentrum Jülich, Jülich, Germany — 4Forschungszentrum Jülich, Jülich, Germany — 5Forschungszentrum Jülich, Jülich, Germany

La0.58Ca0.4Co0.2Fe0.8O3−δ (L58CCF) was synthesized and evaluated as a cathode electrode for intermediate temperature solid oxide fuel cells (IT-SOFC) based on the Y2O3-stabilized ZrO2 (YSZ) electrolyte. The effect of sintering temperature on the L58CCF performance was investigated. The best Area specific resistances (ASRs) for the L58CCF sintered at 950 C were 1.218, 0.447, 0.228, 0.156, 0.099 Ω.cm2 at 600, 650, 700, 750, 800 C, respectively.
