Abstract
Electrochemical characteristics, such as the parameter of resistance (ρ/d) of an intermediate layer at the electrode material/electrolyte interface and the polarization resistance (R η) of the three-phase boundary gas/solid-electrolyte/electrode under study, are studied as a function of the electrode layer thickness, temperature, and oxygen content in the gas phase for electrode materials of the composition (Yb, Y)0.5Ca0.5MnO3. Established is the similarity in the behavior of ρ/d and R η from the above parameters. The determined effect on these characteristics is exerted by the composition of the electrode material. In the temperature range 300–1100 K, at \(P_{0_2 }\) = 102–105 Pa, the least values of the parameter of resistance and polarization resistance are intrinsic to samples with the thickness of the electrode layer 100 mg cm–2 of the composition Y0.5Ca0.5MnO3. For systems studied, the least temperature of establishment of electrochemical equilibrium at the three-phase boundary is 875 (±5) 5 K.
