BaCe1-xYxO3-α (x = 0.1, 0.15) solid electrolytes were prepared via ball milling raw powders of BaCO3, CeO2 and Y2O3, and pressing the powder mixtures into tablets followed by calcining in air. X-ray diffraction analysis indicated that the BaCe0.9Y0.1O3-α and BaCe0.85Y0.15O3-α solid solutions were synthesized at 1250°C and 1400°C, respectively. The solid electrolyte disks were made by grinding the calcined tablets into fine powders, cold isostatic pressing into the shape and sintering at 1550°C in air. The electrochemical impedance spectroscopy measurements revealed that they show useful protonic conduction, up to 2.7×10-2 S/cm at 900°C.
