Description
The paper reports on the doping-influenced evolution of the local structure in a new class of solid electrolytes, BaCe1-xTixO3 and Ba1-yCe1-xYxO3 perovskites, to be used in intermediate temperature fuel cells. The local environments of the Ti, Y and Ce cations were studied by means of X-ray absorption spectroscopy. The Ti XAFS spectra reveal a decrease of the local symmetry of titanium site with increasing doping. The Ce and Y EXAFS functions show a larger amount of oxygen vacancies created by Y doping than that caused by barium understoichiometry.
