Fig. 1From: Electricity generation potential of poultry droppings wastewater in microbial fuel cell using rice husk charcoal electrodesA schematic diagram of a double-chamber PDWW. Electron flows from anode to cathode are through external load as indicated with arrows. Black bars in chambers are the electrodes. Oxidation reaction of PDWW in the anode was shown at the anode while the reduction reaction in the cathode was shown at the cathode. The directions of the flow of protons from anode to cathode through PEM were shown by arrowsBack to article page
