Abstract

NdSrCo_1-xFe_xO_4+δ (0 ≤ x ≤ 1.0) intergrowth oxides have been investigated as cathode materials for intermediate temperature solid oxide fuel cells (IT-SOFCs). All the cathodes prepared by a glycine nitrate process (GNP) indicated single phase intergrowth oxides. The introduction of Fe for Co leads to decrease TEC values and electrical conductivity, and increase polarization resistance and oxygen content. The polarization resistance of NdSrCoO_4+δ composition is 0.16 Ω cm² at 800 °C in air atmosphere, which is the best electrochemical performance compared with other compositions.
