摘要： A carbon nanosphere has at least one opening. The carbon nanosphere is obtained by preparing a carbon nanosphere and treating it with an acid to form the opening. The carbon nanosphere with at least one opening has higher utilization of a surface area and electrical conductivity and lower mass transfer resistance than a conventional carbon nanotube, thus allowing for higher current density and cell voltage with a smaller amount of metal catalyst per unit area of a fuel cell electrode.

摘要： A mesoporous carbon is prepared by mixing 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; carbonizing the impregnated OMS at 800 to 1300° C. by irradiating microwave energy with a power of 100 to 2000 W thereon to form an OMS-carbon composite; and removing the mesoporous silica from the OMS-carbon composite. The method of preparing a mesoporous carbon can significantly reduce a carbonization time by carbonizing a carbon precursor using microwave energy in a silica template compared to a conventional method using a heat treatment. A supported catalyst and a fuel cell include the mesoporous carbon.

摘要： The present invention is related to a short carbon nanotube for a catalyst support. In particular, the short carbon nanotube may be opened at both ends, a length of less than about 300 nm, and an aspect ratio in the range of about 1 to about 15. The short carbon nanotube has a broad surface area and better electric conductivity and is opened at both ends, thereby impregnating a metallic catalyst into the inner side of the carbon nanotube. Also, a catalyst impregnated carbon nanotube has a broad effective specific surface area, and thus, has an improved efficiency of catalyst utilization, can reduce an amount of the catalyst used and can efficiently diffuse a fuel. Accordingly, when catalyst impregnated carbon nanotube is used in a fuel cell, etc., improvements can be made in the pricing, power density of an electrode, and energy density of a fuel cell.

A supported catalyst having a desired amount of loaded catalytic metal particles can be obtained 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 catalytic metal, and reducing the remaining portion of the catalytic metal by a secondary liquid phase reduction reaction. 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： Provided are a CNT-mesoporous silica composite, a CNT-mesoporous carbon composite, a supported catalyst using the CNT-mesoporous carbon composite as a support, and a fuel cell using the supported catalyst as the anode, cathode, or both anode and cathode. The CNT-mesoporous carbon composite is prepared using the CNT-mesoporous silica composite. The CNT-mesoporous carbon composite has a high electrical conductivity due to the CNTs contained therein, and thus, when the CNT-mesoporous carbon composite is used in an electrode of a fuel cell, the fuel cell has a remarkably improved performance relative to the conventional catalyst support which does not contain CNTs.
