    摘要： A carbon nanotube (“CNT”) gas sensor includes a substrate, an insulating layer formed on the substrate, electrodes formed on the insulating layer, and CNT barriers that protrude higher than the electrodes in spaces between the electrodes to form gas detecting spaces. A method of manufacturing the gas sensor includes forming an insulating layer on a substrate, forming an electrode pattern on the insulating layer, coating CNT paste having a thickness greater than a thickness of electrodes in the electrode pattern on the electrodes and the insulating layer, and patterning and firing the carbon nanotube paste, including using a photolithography method, to retain only portions of the CNT paste coated on spaces between the electrodes.

    摘要： A carbon nanotube, a method of preparing the same, a supported catalyst including the same, and a fuel cell using the supported catalyst are provided. The method of preparing the carbon nanotube includes: depositing a metal catalyst in single wall nanotubes and growing multi wall nanotubes over the single wall nanotubes using the metal catalyst. The carbon nanotubes of the present invention have satisfactory specific surface area and low surface resistance. Thus, the carbon nanotubes perform remarkably better than a conventional catalyst carrier. Accordingly, the carbon nanotubes, when used as a catalyst carrier of an electrode for a fuel cell, can improve the electrical conductivity of the fuel cell. In addition, a fuel cell employing the electrode has excellent efficiency and overall performance.
