Two functionally graded layers between the electrolyte and adjacent electrodes were prepared by atmospheric plasma spraying (APS) for solid oxide fuel cells (SOFCs). Both the porosity and material compositions gradually vary in the two graded layers. The SOFC with the graded layers has higher electronic conductivity and far lower interface resistance than that without graded layers.
