Intermediate temperature (IT) solid oxide fuel cell (SOFC) development is hindered by slow oxygen reduction reaction (ORR) and poor CO2 tolerance at the cathode electrode. Here, we present a successful synthesis of composite material consisting double perovskite structure Sr2CoNbO6−δ (SCNO) fluorite Sm0.2Ce0.8O2−δ (SDC), using one-pot method. Integrating SDC to form SCNO–SDC substantially augments number active sites, resulting in high ORR activity lower polarization resistance. Forming tight, coherent interface between SCNO particles advantageous reducing thermal expansion coefficient significantly improving ion transport creating 3D pathway through self-assembled growth particles. At 700 °C, SOFC (full cell) utilizing exhibits peak power density (PPD) 0.786 W cm–2, surpassing PPD 0.602 cm–2 attained alone. Furthermore, upon exposure CO2, demonstrated remarkable performance recovery tolerance. This study offers insights into functioning IT-SOFCs with enhanced electrochemical long-term stability.
