Abstract
A method for forming a solid oxide fuel cell (SOFC) article includes forming a SOFC unit cell in a single, free-sintering process, wherein the SOFC unit cell is made of an electrolyte layer, an interconnect layer, a first electrode layer disposed between the electrolyte layer and the interconnect layer. The electrolyte layer of the SOFC unit cell is in compression after forming.
