Electrochemical performance of the Pr2CuO4-based cathode materials in planar anode-supported IT-SOFCs
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.
期刊介绍：
The Journal of Solid State Electrochemistry is devoted to all aspects of solid-state chemistry and solid-state physics in electrochemistry.
The Journal of Solid State Electrochemistry publishes papers on all aspects of electrochemistry of solid compounds, including experimental and theoretical, basic and applied work. It equally publishes papers on the thermodynamics and kinetics of electrochemical reactions if at least one actively participating phase is solid. Also of interest are articles on the transport of ions and electrons in solids whenever these processes are relevant to electrochemical reactions and on the use of solid-state electrochemical reactions in the analysis of solids and their surfaces.
The journal covers solid-state electrochemistry and focusses on the following fields: mechanisms of solid-state electrochemical reactions, semiconductor electrochemistry, electrochemical batteries, accumulators and fuel cells, electrochemical mineral leaching, galvanic metal plating, electrochemical potential memory devices, solid-state electrochemical sensors, ion and electron transport in solid materials and polymers, electrocatalysis, photoelectrochemistry, corrosion of solid materials, solid-state electroanalysis, electrochemical machining of materials, electrochromism and electrochromic devices, new electrochemical solid-state synthesis.
The Journal of Solid State Electrochemistry makes the professional in research and industry aware of this swift progress and its importance for future developments and success in the above-mentioned fields.
