The diffusivities of the ATLS electrolyte materials are higher compared
to yttria stabilized zirconia which is an industrial standard electrolyte
material. In Fig. 6, oxygen self-diffusion data in 10YSZ are
plotted together with the diffusivities of the ATLS samples. It is obvious
that the diffusivities of the ATLS are especially at lower temperatures
higher. The activation enthalpy for oxygen diffusion in YSZ is higher as
compared to the ATLS used in this study.
