Ca substituion instead of Sr in La$_{0.58}$Sr$_{0.4}$Co$_{0.2}$Fe$_{0.8}$O$_{3-δ}$ as a cathode electrode for IT-SOFCs (2404.12972v1)
Published 19 Apr 2024 in cond-mat.mtrl-sci
Abstract: La${0.58}$Ca${0.4}$Co${0.2}$Fe${0.8}$O$_{3-\delta}$ (L58CCF) was synthesized and evaluated as a cathode electrode for intermediate temperature solid oxide fuel cells (IT-SOFC) based on the Y$_2$O$_3$-stabilized ZrO$_2$ (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 ${\circ}$C were 1.218, 0.447, 0.228, 0.156, 0.099 $\Omega.cm{2}$ at 600, 650, 700, 750, 800 ${\circ}$C, respectively.
