description The invention relates to a preparation method of a composite cathode of a microbial fuel cell. The method comprises the steps of preparing a polyethylene (PE) solution, immersing a piece of carbon cloth into the PE solution for 2h to 3h, taking out the carbon cloth, drying the carbon cloth by utilizing an air heater, and then calcining the carbon cloth in a calcining furnace for 1 to 5 minutes at the temperature of 350 to 380 DEG C; adding a sulfuric acid solution into carbon black and silver chloride, stirring for 15 to 20 minutes, adding PE solution and isopropanol, and separating in a centrifugal machine for 5 minutes; coating the front surface of the carbon cloth with the carbon black solution, drying the carbon cloth, and calcining the dried carbon cloth for 30 to 40 minutes. The preparation method has the advantages that the conductivity of the prepared modified cathode is obviously improved.
