Abstract
The structure, thermal expansion coefficient, and electroconductivity of YBa2(Cu1−x Al x )3O6+δ (x = 0.0–0.9) were studied at 20 to 900°C in air. The most conducting compositions of YBa2(Cu1−x Me x )3O6+δ (Me = Al, Co, Fe) were determined. The electrochemical activity of electrodes with the most conducting compositions of YBa2(Cu1−x Me x )3O6+δ (Me = Al, Co, Fe) was studied in a wide polarization range in the contact with 0.9ZrO2 + 0.1Y2O3 solid electrolyte in air at the temperatures of 700 to 900°C.
