Ca substituion instead of Sr in La_0.58Sr_0.4Co_0.2Fe_0.8O_3−δ as a cathode electrode for IT-SOFCs — •Majid Jafari¹, Fatemeh Yadollahi Farsani², Norbert Menzler³, Christian Lenser⁴, and Fabian Grimm⁵ — ¹Plön, Germany — ²Isfahan university of technology, Isfahan, Iran — ³Forschungszentrum Jülich, Jülich, Germany — ⁴Forschungszentrum Jülich, Jülich, Germany — ⁵Forschungszentrum Jülich, Jülich, Germany

La_0.58Ca_0.4Co_0.2Fe_0.8O_3−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.
