High performance Gd~(3+) and Y~(3+) co-doped ceria-based electrolytes for intermediate temperature solid oxide fuel cells

摘要

Co-doped ceria of Ce_(1-x)Gd_(x-y)Y_yO_(2-0.5x), wherein x = 0.15 and 0.2, 0 = y = x, were prepared by glycine-nitrate method. Their structures and ionic conductivities were characterized by X-ray diffraction (XRD) and AC impedance spectroscopy (IS). All
