NOVELTY - Mixture of silica oligomer, condensation-polymerizable carbon-containing compound used as carbon precursor and liquid carrier is impregnated in air hole of template. The precursor is polymerized. The polymer is thermally decomposed and carbonized and silica oligomer is removed to obtain carbon molecular material. The oligomer is removed by processing template with solution which selectively dissolves silica.    USE - In catalyst for fuel cells (claimed) such as polymer electrolyte membrane fuel cell and direct methanol fuel cell, for motor vehicle, domestic electric power generation system, mobile communication equipment, medical equipment, space commercial equipment and portable electronic device.    ADVANTAGE - Carbon molecular material with improved structural regularity is manufactured easily. The fine air hole fraction in the material is increased.    DETAILED DESCRIPTION - A mixture of silica oligomer, condensation-polymerizable carbon-containing compound used as carbon precursor and liquid carrier is impregnated in air hole of template. The carbon precursor in the air hole is polymerized to obtain a polymer. The polymer is thermally decomposed and carbonized, and silica oligomer is removed by processing the template with a solution which selectively dissolves silica, to obtain carbon molecular material. The template is mesoporous silica molecular material. INDEPENDENT CLAIMS are included for the following:    (1) carbon molecular material which contains fine carbon rods mutually connecting intermediate size carbon rods. The intermediate size carbon rod is supported with fine carbon rod and an internal structure is formed;    (2) catalyst for fuel cell which contains the carbon molecular material as catalyst support having air hole and catalyst metal contained in the air hole; and    (3) fuel cell containing the catalyst.    DESCRIPTION OF DRAWING(S) - The figure shows the X-ray diffraction pattern of the carbon molecular material. (Drawing includes non-English language text).
