Abstract
Provided are aligned carbon nanotubes for a fuel cell having a large surface area, a nanocomposite that includes the aligned carbon nanotubes loaded with highly dispersed nanoparticles of a metallic catalyst, methods of producing the carbon nanotubes and the nanocomposite, and a fuel cell including the nanocomposite. In the nanocomposite, nanoparticles of the metallic catalyst are uniformly distributed on external walls of the nanotubes. A fuel cell including the nanocomposite exhibits better performance.
