Аннотация:Diferent types of planar anode-supported solid oxide fuel cells (SOFCs) with Pr2CuO4(PCO)-based cathode materials werefabricated. A vacuum aerosol deposition method was used to form a thin gas-tight electrolyte layer. The infuence of thePCO cathode formation on the electrochemical performance and impedance characteristics of the obtained SOFC sampleswas investigated. It was shown that the fuel cell with bifunctional cathode based on PCO exhibited high power density 265mW/cm2 at 800 °C. The impedance spectroscopy results show rather low ohmic losses for the investigated fuel cells. Thelowest polarization resistance value (0.43 Ω cm2 at 800 °C) was obtained for the fuel cell with the bifunctional PCO-basedcomposite cathode. The results obtained allow to consider the PCO-based composite cathode as a promising cathode material for intermediate-temperature SOFCs.
