NOVELTY - A fuel battery with sulfonamide type anion exchange membrane comprises aromatic polymer or Nafion (RTM: perfluoro-sulfonic acid polymer) as substrate material; and is prepared by introducing sulfonamide on the benzene ring of the aromatic polymer or the side chain of the Nafion (RTM: perfluoro-sulfonic acid polymer) and subjected to alkalization.    USE - A fuel battery with sulfonamide type anion exchange membrane.    ADVANTAGE - The fuel battery is cheap and environment-friendly; and has simple preparation method, high ion exchange capacity, good conductivity and stability, desired mechanical strength, and maximum output power density of 50-120 mW/cm2.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) preparation of an anion exchange membrane comprising mixing (pts. wt) sulfonated polymer (1-3) and 95-98% concentrated sulfuric acid (550-600), stirring at 30-40 degrees C for 2-3 hours, dipping obtained product in iced water mixture to obtain grain shaped deposition, washing obtained product with deionized water, filtering, neutralizing the filter cake, drying at 50-60 degrees C for 6-12 hours, drying further at 100-150 degrees C for 12-24 hours, mixing (pts. wt.) dried product (1-2) and acyl chlorination agent (25-50), heating at 90-100 degrees C for 7-8 hours, cooling to room temperature, stirring for 4 hours, filtering, vacuum drying at 60-80 degrees C for 12 hours, adding non-proton polar solvent (5-8 wt.%) to the product, heating at 60-80 degrees C, volatilizing the solvent, vacuum drying at 100-120 degrees C for 12-24 hours, quaternizing obtained film, dipping obtained film in a tertiary amine reagent for 24-48 hours, and soaking in 0.5-1 M sodium hydroxide aqueous solution for 24-30 hours; and (2) preparation of the fuel battery comprising mixing (pts. wt.) aromatic polymer or Nafion (RTM: perfluoro-sulfonic acid polymer) (1-2) and acyl chlorination agent (25-50), reflux heating at 90-100 degrees C for 7-8 hours, cooling to room temperature for 4 hours, vacuum drying at 60-80 degrees C for overnight, soaking obtained product in tertiary amine reagent for 24-48 hours, soaking in deionized water, washing, and adding 0.5-1 M sodium hydroxide aqueous solution for 24-30 hours.
