NOVELTY - Carbon material is mixed in 59-60 volume% isopropanol solution and impregnated for 8-24 hours. The carbon material is washed with deionized water for 5-10 times and dried at 80-150 degrees C. The obtained sample is placed in anode solution or formic acid solution and impregnated for 8-12 hours. The sample is washed with deionized water 5-10 times and dried at 80-110 degrees C for 6-8 hours to obtain anode material. The concentration of formic acid solution is 10-88 %mass.    USE - Manufacture of anode for microbiological fuel cell.    ADVANTAGE - The anode for microbiological fuel cell is easily, stably and economically manufactured.    DETAILED DESCRIPTION - Carbon material is mixed in 59-60 volume% isopropanol solution and impregnated for 8-24 hours. The carbon material is washed with deionized water for 5-10 times and dried at 80-150 degrees C. The obtained sample is placed in anode solution or formic acid solution and impregnated for 8-12 hours. The sample is washed with deionized water 5-10 times and dried at 80-110 degrees C for 6-8 hours to obtain anode material. The concentration of formic acid solution is 10-88 %mass. The anode solution is formed using phosphate buffer, 0.31 g/L ammonium chloride, 0.13 g/L potassium chloride, 12.5 mL/L mineral solution and 1 g/L sodium acetate. The anode solution is consumed by microorganism. When chemical oxygen demand is reduced to 80-120 mg/L or voltage is reduced to less than 10-40 mV, the remaining solution is added. The phosphate buffer solution contains 11.47 g/L disodium hydrogen phosphate decahydrate and 2.75 g/L sodium hydrogen phosphate dihydrate. The mineral solution contains 1.5 g/L nitrilo triacetate, 6.15 g/L magnesium sulfate heptahydrate, 0.5 g/L manganese sulfate hydrate, 1 g/L sodium chloride, 0.1 g/L iron sulfate heptahydrate, 0.1 g/L calcium chloride dihydrate, 0.1 g/L cobalt chloride hexahydrate, 0.13 g/L zinc chloride, 0.01 g/L copper sulfate pentahydrate, 0.01 g/L aluminum potassium sulfate dodecahydrate, 0.01 g/L boric acid, 0.054 g/L sodium molybdenum oxide dihydrate, 0.024 g/L nickel chloride hexahydrate, 0.025 g/L sodium tungsten oxide dehydrate and remaining water.
