20100004121 | Short carbon nanotube for catalyst support, method of preparing the same, catalyst impregnated carbon nanotube using the same, and fuel cell using the catalyst impregnated carbon nanotube - 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. | 01-07-2010 |
