摘要：
BaCeO3-based ceramics with Gd, Yb and Nd dopants were synthesized using conventional ceramic powder methods and were characterized by the following measurements: complex impedance to measure the bulk and grain boundary conductivity; the water uptake or loss in different environments; and the influence of normal and heavy water uptake on the conductivity of the samples. Conductivity and gravimetric measurements of all the samples show strong evidence of proton conduction, including a classical hydrogen/deuterium isotope effect. The influence of the gas ambient and the temperature on water uptake during annealing pretreatment is demonstrated and may be a significant factor in the discrepancies in the literature of these materials.
