- Аннотация: The conditions of formation of electrode/electrolyte interfaces LaSrCuO4-delta|Ce0.9Gd0.1O2-delta are optimized. It is shown that electrode layers formed by the screen printing method have better developed surfaces and are more uniform and strong as compared with thick film layers applied by a brush. Symmetric LaSrCuO4-delta|Ce0.9Gd0.1O2-delta|LaSrCuO4-delta cells with porous electrodes are studied by impedance spectroscopy and cyclic voltammetry in the temperature range of 773-1173 K at the oxygen partial pressure of (28-2.1) x 10(4) Pa. The oxygen process is shown to be limited by the charge transfer across the electrode/electrolyte interface. The exchange currents are calculated in the temperature range of 773-1173 K to amount from 1 x 10(-3) to 3.5 x 10(-2) A/cm(2), which points to the high reversibility of the electrode/electrolyte interface with respect to oxygen.
