Аннотация
The behavior of polarization resistance of 50% Ni + 50% Zr0.9Sc0.1O1.95 electrodes in contact with Zr0.84Y0.16O1.92 electrolyte both in their initial state and after the introduction of cerium oxide into their porous structure is studied by the method of electrochemical impedance. The 1500 h experiments carried out at 800°С in the 60% H2O + 40% H2 gas medium demonstrate that the degradation rate of the electrodes in their initial state is somewhat lower than after the introduction of CeO2, while the initial polarization resistance of thus modified electrodes is 5-times lower. It is found that the introduction of cerium oxide can lower down the polarization resistance of electrodes subjected to short-term 500 h exposures.
