Electrical and Electrochemical Properties of La2NiO4+δ-Based Cathodes in Contact with Ce0.8Sm0.2O2-δ Electrolyte☆
2014
Abstract The current work focuses on the investigation of the structural and electrical properties of La 2 NiO 4±δ , La 1.7 Sr 0.3 NiO 4±δ and La 1.7 Ca 0.3 NiO 4±δ layered perovskites and electrochemical performance of the cathodes on their base in contact with the Ce 0.8 Sm 0.2 O 1.9 electrolyte with special attention given to the influence of the introduction of the sintering additives (CuO, Bi 0.75 Y 0.25 O 1.5 ) into cathode layers on their in-plane and polarization resistances. Studies by the dc four-probe technique and impedance spectroscopy were performed on the samples with/without the collector layer on a base of LaNi 0.6 Fe 0.4 O 3 with different sintering temperatures of the electrode layers.
