NOVELTY - A metal oxide-doped carbon gel carrier is prepared by mixing resorcinol and solvent (A), preparing solution (B), adding formaldehyde solution with concentration of 20-40%, stirring at 20-100 degrees C, forming sol-gel precursor, dissolving soluble metal salt in solvent (Q), mixing, heating, refluxing, adding coordination compound, reacting, obtaining metal complex, diluting resultant product with 0.5-2 M aqueous ammonia or 0.5-2 M oxalic acid, adjusting pH to 7, dripping sol-gel precursor, obtaining gel (C), drying, aging, grinding, obtaining solid powder (D), and cooling.    USE - Metal oxide-doped carbon gel carrier is used for proton exchange membrane fuel cell (claimed).    ADVANTAGE - The metal oxide-doped carbon gel carrier has excellent stability, activity and electrochemical property.    DETAILED DESCRIPTION - A metal oxide-doped carbon gel carrier comprises resorcinol, formaldehyde, coordination compound and soluble metal salt as raw materials, and is prepared by mixing 1 g resorcinol and 0.1-10 ml solvent (A), preparing solution (B), adding formaldehyde solution with concentration of 20-40%, stirring at 20-100 degrees C, forming sol-gel precursor, dissolving soluble metal salt in solvent (Q) in a volume ratio of 10:1-1:10, mixing, heating to 30-160 degrees C, refluxing, adding coordination compound, reacting for 0.5-12 hours, obtaining metal complex, diluting resultant metal complex with solvent (Q) to 2-10 times of original volume, diluting resultant product with 0.5-2 M aqueous ammonia or 0.5-2 M oxalic acid, adjusting pH to 7 at 25-70 degrees C, dripping sol-gel precursor, obtaining gel (C), drying, aging for 3-12 days, grinding, obtaining solid powder (D), maintaining the solid powder (D) in inert atmosphere at 600-1200 degrees C for 1-10 hours, and cooling to room temperature. The molar ratio of resorcinol and formaldehyde is 1:1-4:1. The molar ratio of coordination compound and soluble metal salt is 20:1-1:20. The volume ratio of sol-gel precursor and metal complex is 10:1-1:10.
