NOVELTY - The microbial fuel cell comprises anode tanks, a cathode tank, and a proton exchange membrane that connects the cathode tank with anode tank by a non conductive epoxy membrane. Each of the anode tanks comprises an anodic electrode rod suspended from a top of the anode tank and coupled with an anode, and a sampling port for addition and removal of solution. The cathode tank comprises cathodic electrode plates suspended from a top of the cathode tank and coupled together, and a sampling port for addition and removal of solution. The cathodic electrode plates are graphite plates.    USE - The microbial fuel cell is useful for generating electricity from wastewater including wastewater from sewage treatment or industrial waste, artificial wastewater, paper industry wastewater, beer brewery wastewater, sugar industry wastewater, dairy wastewater, municipal wastewater, potato wastewater and tannery wastewater.    ADVANTAGE - The microbial fuel cell continuously generates the electricity with increased yield in an environmentally friendly and an economical manner.    DETAILED DESCRIPTION - The microbial fuel cell comprises anode tanks, a cathode tank, and a proton exchange membrane that connects the cathode tank with anode tank by a non conductive epoxy membrane. Each of the anode tanks comprises an anodic electrode rod suspended from a top of the anode tank and coupled with an anode, and a sampling port for addition and removal of solution. The cathode tank comprises cathodic electrode plates suspended from a top of the cathode tank and coupled together, and a sampling port for addition and removal of solution. The cathodic electrode plates are graphite plates arranged parallel to each other. The anodic electrodes are plain carbon rod. The anodic tanks have anaerobic condition maintained by continuous supply of nitrogen and carbon dioxide gases at a ratio of 80:20. The proton exchange membrane restricts the direct transfer of electron between anode tank and cathode tank. The anode tank is filled with wastewater.    DESCRIPTION OF DRAWING(S) - The figure shows a schematic view of a microbial fuel cell.
