Mesoporous carbon composite, method of preparing the same, and fuel cell using the mesoporous carbon composite

A mesoporous carbon composite formed by a method comprising:

• impregnating an ordered mesoporous silica (OMS) with a carbon precursor mixture comprising a carbon precursor, an acid, and a solvent;
• heat-treating and carbonizing the impregnated OMS to form an OMS-carbon composite;
• mixing the OMS-carbon composite with a monomer that forms an electrically conductive polymer and a solvent to provide a surface of the OMS-carbon composite with the monomer that forms an electrically conductive polymer;
• polymerizing the monomer to obtain an electrically conductive polymer-coated OMS-carbon composite;
• removing the OMS from the electrically conductive polymer-coated OMS-carbon composite to obtain an electrically conductive polymer-coated on only an outer surface of the mesoporous carbon having ordered mesopores;
• and
• doping the electrically conductive polymer-coated mesoporous carbon with an organic electrolyte comprising a lithium salt and an organic solvent to form the mesoporous carbon composite
• wherein the mesoporous carbon composite has a main peak at a Bragg angle 2θ for a CuK-α X-ray wavelength of 1.54 Å at 1.0±0.4 degrees, and one or more peaks appear within 10 degrees.
