Method for producing cerium-based composite oxide, solid oxide fuel cell, and fuel cell system

On the other hand, the possibility of estimating the dopant ratio of a metal element to each ceria crystalline particle using integral-width or half-width obtained by xrd was considered as follows: an xrd peak is shifted depending on the dopant ratio of la to ceria; when la increases, an xrd peak is shifted to a lower angle; in xrd performed on a raw material obtained by mixing ceria crystalline particles having different dopant ratio, peaks corresponding to the respective dopant ratio exist close to each other; as a result, a peak width is widened; accordingly, the dopant ratio of a metal element to each ceria crystalline particles are supposed to vary when integral-width and half-width obtained by xrd are large. Thus, it was revealed for the first time that integral-width and half-width obtained by xrd indicate variations in dopant ratio.
