Abstract

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.
