摘要
The present invention relates to a multi-layered and multifunctional cathode in solid oxide fuel cells having high conductivity, high catalytic activity, minimized coefficient of thermal expansion (CTE) mismatch, excellent compatibility to other portion of the fuel cell, and reduced temperature operation. The cathode comprises a conductive layer, a catalyst layer and a grade composition layer. The conductive layer has a first density, the catalyst layer has a second density that is less than the first density, and the graded composition layer is characterized by a graded electronic conductivity and a graded ionic conductivity.
