    摘要: Disclosed is a dense thin film, a fuel cell using the same and fabrication methods thereof. A method for fabricating a dense thin film comprises (1) forming a first thin film on a porous surface, and (2) forming, on a surface of the first thin film, a second thin film made of a homogeneous material with respect to the first thin film, thereby removing pinholes of the first thin film. The method for fabricating a dense thin film may comprise (1′) forming a first thin film on a porous surface, (2′) forming, on a surface of the first thin film, a second thin film made of a to heterogeneous material with respect to the first thin film, thereby removing pinholes of the first thin film, and (3′) etching a surface of the second thin film. A dense thin film comprises a porous material, a first thin film formed on a surface of the porous material and having pinholes, a blocking material including a homogeneous or heterogeneous material with respect to the first thin film and configured to block the pinholes, and a second thin film including a homogeneous or heterogeneous material with respect to the first thin film and formed on a surface of the first thin film.
