Abstract
The present invention relates to a novel method for preparing a BZCYYb material to be used in a solid oxide fuel cell. In particular, the method comprises mixing particular nano-sized and micro-sized ingredients and the size selection provides greatly improved performance characteristics of the resulting material. In particular, barium carbonate powder, zirconium oxide powder having particle diameters in the nanometer range, and cerium oxide powder having particle diameter in the micrometer range are used together with ytterbium oxide powder, and yttrium oxide powder.
