    Abstract: PURPOSE: A solid oxide fuel cell is provided to overcome a difference of thermal expansion coefficient with an electrolytic material and to improve structural stability at SOFC operation temperature by forming a nanostructured electrolyte-air electrode composite thin layer with high catalytic activity which is mixed to molecular size by using a thin film deposition. CONSTITUTION: A solid oxide fuel cell comprises a fuel electrode support, a solid electrolyte layer (10) formed on the fuel electrode support, and a nano structure composite air electrode layer(20) formed on the solid electrolyte layer. The nanostructured composite air electrode layer comprises an electrode material and an electrolyte material which are mixed to a molecular size but does not forms a single phase by the materials being not reacted or solved to each other. The ratio of the electrode material and the electrolyte material in the nanostructured composite air electrode layer is 2:8-8:2. A particle size of the composite air electrode layer is 100 nm or less.
