摘要： A method of preparing a supported catalyst includes dissolving a cation exchange polymer in alcohol to prepare a solution containing cation exchange polymer; mixing the cation exchange polymer containing solution with a catalytic metal precursor or a solution containing catalytic metal precursor; heating the mixture after adjusting its pH to a predetermined range; adding a reducing agent to the resultant and stirring the solution to reduce the catalytic metal precursor; mixing the resultant with a catalyst support; adding a precipitating agent to the resultant to form precipitates; and filtering and drying the precipitates. The method of preparing a supported catalyst can provide a highly dispersed supported catalyst containing catalytic metal particles with a reduced average size regardless of the type of catalyst support, which provides better catalytic activity than conventional catalysts at the same loading amount of catalytic metal.

摘要： Carbon nanotubes for use in a fuel cell, a method for fabricating the same, and a fuel cell using the carbon nanotubes for its electrode are provided. The internal and external walls of the carbon nanotubes are doped with nano-sized metallic catalyst particles uniformly to a degree of 0.3-5 mg/cm2. The carbon nanotubes are grown over a carbon substrate using chemical vapor deposition or plasma enhanced chemical vapor deposition. Since the carbon nanotubes have a large specific surface area, and metallic catalyst particles are uniformly distributed over the internal and external walls thereof, the reaction efficiency in an electrode becomes maximal when the carbon nanotubes are used for the electrode of a fuel cell. The carbon nanotubes fabricated using the method can be applied to form a large electrode. The carbon nanotubes grown over the carbon substrate can be readily applied to an electrode of a fuel cell, providing economical advantages and simplifying the overall electrode manufacturing process. A fuel cell using as the carbon nanotubes for its electrode provides improved performance.

摘要： A method of preparing a mesoporous carbon includes mixing a mesophase pitch, a carbon precursor, an acid, and a solvent to obtain a carbon precursor mixture; impregnating an ordered mesoporous silica (OMS) with the carbon precursor mixture; heat-treating and carbonizing the impregnated OMS to form an OMS-carbon composite; and removing the OMS from the OMS-carbon composite. The mesoporous carbon uses the mesophase pitch and the carbon precursor to reduce sheet resistance, and thus can efficiently transfer electric energy. Such mesoporous carbon can be used as a conductive material of electrodes for fuel cells. When the mesoporous carbon is used as a support for catalysts of electrodes, a supported catalyst containing the support can be used to manufacture a fuel cell having high efficiency.
