Electrical and Electrochemical Properties of La2xCaxNiO4 and La2xCaxNiO4–Ce0.8Sm0.2O1.9 Cathode Materials for Intermediate Temperature SOFCs


Article Preview

The present work focuses on the electrical properties of La2xCaxNiO4+δ (x=0–0.4) and the electrochemical performance of the cathodes based on these materials with a LаNi0.6Fe0.4O3-δ current collector in contact with a Ce0.8Sm0.2O1.9 electrolyte. The effect of the sintering temperature on the polarization resistance of La1.7Ca0.3NiO4+δ–Ce0.8Sm0.2O1.9 composites of different content has been studied by an impedance spectroscopy method. The composite electrode 50 wt.% La1.7Ca0.3NiO4+δ – 50 wt.% Ce0.8Sm0.2O1.9 sintered at the temperature below 1300°C has showed the lowest polarization resistance value equal to 0.27 Ωcm2 and in case of PrOx infiltration 0.033 Ωcm2 at 800°C in air.
