Abstract
A conductive carbon carrier for a fuel cell having at least a surface layer graphitized, characterized in that the dimension (La) in a six-membered ring face (carbon plane) direction of a crystallite measured by X-ray diffraction is 4.5 nm or more. This carbon carrier improves the durability in a fuel cell and enables operation for a long period of time.
