Disclosed is a carbon catalyst that prevents the coarsening of the particle size of a carbon nanoshell structure that causes a reduction in oxygen reduction activity. A step of preparing a carbon precursor polymer, a step of mixing a transition metal or a transition metal compound with the carbon precursor polymer, and fiberizing a carbon precursor polymer and a mixture of the transition metal or transition metal to form fibers. A carbon catalyst is manufactured by the process of obtaining, and the process of carbonizing a fiber. [Selection figure] None |
