摘要
PURPOSE: A solid oxide fuel cell and a manufacturing method thereof are provided to prevent the defect occurrence by the sintering difference at a multi-layered structure by controlling the pore size distribution, and the surface roughness. CONSTITUTION: A solid oxide fuel cell comprises the following: a porous supporter; a dense electrolyte thin film; and a nanoporous layer smaller including a pore on the surface where contacting with the dense electrolyte thin film with the size smaller than the thickness of the dense electrolyte thin film and the pore size of the porous supporter. The nanoporous layer is formed in between the porous supporter and the dense electrolyte thin film. The nanoporous layer is a coating film of a metal oxide sol dispersed with nanopowder.
