摘要

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