摘要： 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 supported catalyst, a supported catalyst prepared by the method, and a fuel cell using the supported catalyst. In particular, a method of preparing a supported catalyst by preparing a primary supported catalyst containing catalytic metal particles that are obtained by a primary gas phase reduction reaction of a portion of the final loading amount of a catalytic metal, and reducing the remaining portion of the catalytic metal by a secondary liquid phase reduction reaction using the primary supported catalyst. The supported catalyst contains catalytic metal particles having a very small average particle size, which are uniformly distributed on a carbon support at a high concentration, and thus exhibits maximal catalyst activity. A fuel cell produced using the supported catalyst has improved efficiency.

摘要： A catalyst coated membrane (CCM) comprising an anode catalyst layer having a first catalyst layer composed of a non-supported catalyst and a second catalyst layer composed of a supported catalyst, a cathode catalyst layer composed of a supported catalyst, and an electrolyte membrane interposed between the anode catalyst layer and a cathode catalyst layer, the first catalyst layer of the anode catalyst layer being disposed adjacent to the electrolyte membrane; a membrane electrode assembly (MEA) comprising the catalyst coated membrane; a method of preparing the membrane electrode assembly; and a fuel cell comprising the membrane electrode assembly, are provided. The CCM, which comprises a bilayered anode catalyst layer including the first catalyst layer composed of a non-supported catalyst and the second catalyst layer composed of a supported catalyst, exhibits reduced electrical resistance and interfacial resistance, and has increased catalyst availability. The use of the CCM and an MEA having the same results in a decrease in the interfacial resistance between the electrodes and the electrolyte membrane, a decrease in the amount of the catalyst used in the electrode catalyst layer, and a decrease in the thickness deviation in the electrode layers. The fuel cell employing the MEA exhibits maximal activity of the supported catalyst, and has improved cell characteristics such as output voltage, output density, efficiency, and the like.
