Compatibility of NiO-SDC and NiO-Fe Anodes with Samarium-Doped Ceria Carbonate (SDCC) Electrolyte Intermediate-Temperature Solid Oxide Fuel Cells

Abstract:

Samarium-doped ceria carbonate (SDCC) is a potential electrolyte material for solid oxide fuel cells (SOFCs). It has exhibited high ionic conductivity while operating at intermediate and low temperatures. In this research, symmetrical cells supported by SDCC electrolyte consisting of NiO–SDC and NiO–Fe anodes were fabricated by using the dry-pressing and slurry-coating techniques. The cross-sectional morphology of the symmetrical cells was analyzed via field-emission scanning electron microscopy. Electrochemical impedance spectroscopy was used to test the electrochemical performance of the cells. The results of electrochemical performance test showed that both symmetrical cells exhibited low area surface resistance (ASR) at 600 °C. The ASR of the Ni–Fe/SDCC/Ni–Fe symmetrical cell was 1.05 Ω·cm², lower than that of the Ni–SDC/SDCC/Ni–SDC cell (20.30 Ω·cm²). Overall, this study proved that Ni–Fe alloy can be used in combination with SDCC electrolyte for intermediate-temperature SOFC applications.
