Nikonov, A.V., Semenova, I.V., Pavzderin, N.B. et al. The Effect of a Dense Layer with Mixed Ionic–Electronic Conduction on the Characteristics of an SOFC Cathode. Russ J Electrochem 58, 490–501 (2022). https://doi.org/10.1134/S102319352206009X

The effects of dense layers of La1 – xSrxCo1 – yFeyO3 – δ (x = 0.1, 0.2, 0.3, 0.4; y = 0, 0.2, 0.8) cathode materials located on the electrolyte surface on the polarization characteristics of porous cathodes has been studied. The electrode characteristics were measured by impedance spectroscopy on symmetric samples with three types of electrodes: a porous electrode, a dense electrode, and a double layer electrode consisting of dense and porous layers. It has been shown that the introduction of the dense layer into the cathode structure can have both a positive and a negative effect on the polarization resistance. It has been found that the effect of the dense layer on the high-frequency contribution to the polarization resistance correlates with the surface specific resistance of the dense layer. The layers from La1 – xSrxCoO3 (x = 0.1, 0.3) highly conductive materials lead to a decrease of polarization resistance while the layers from La1 – xSrxCo1 – yFeyO3 – δ (x = 0.2, 0.4; y = 0.2, 0.8) materials lead to an increase of polarization resistance.
