A sulfur-containing mesoporous carbon that has mesopores with an average diameter of 2 to 10 nm, a method of preparing the same, a catalyst containing the mesoporous carbon as a catalyst support, and a fuel cell using the catalyst in which the sulfur-containing mesoporous carbon has a good affinity for and adhesion to catalyst particles so as to strongly support the catalyst particles due to the sulfur atoms substituting for carbons in an OMC carbon skeleton structure. The growth of metal catalyst particles is prevented when heat-treating the metal catalyst particles. The catalyst using the sulfur-containing mesoporous carbon can be applied to a fuel cell to prevent a reduction in catalytic activity due to increased particle size by an accumulation of catalyst particles. The catalyst containing the sulfur-containing mesoporous carbon as a catalyst support can be used to manufacture a fuel cell having an improved performance. |
