摘要：

BaCe(1-x)Y(x)O(3-alpha) (x = 0.1, 0.15) solid electrolytes were prepared via ball milling raw powders of BaCO(3), CeO(2) and Y(2)O(3), and pressing the powder mixtures into tablets followed by calcining in air. X-ray diffraction analysis indicated that the BaCe(0.9)Y(0.1)O(3-alpha) and BaCe(0.85)Y(0.15)O(3-alpha) solid solutions were synthesized at 1250 degrees C and 1400 degrees 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 degrees C in air. The electrochemical impedance spectroscopy measurements revealed that they show useful protonic conduction, up to 2.7x10(-2) S/cm at 900 degrees C.
