In the present study, electricity generation with waste water as substrate was investigated in a two compartment biofuel cell with two different combinations of electrodes and membrane. Two proton exchange membranes namely nafion and agar salt bridge and aluminum as electrode were used in the biofuel cell. It was found that biofuel cells operated with nafion produce maximum voltage 0.504 V with a current density of 0.1 A/m2 whereas in case of agar salt bridge maximum voltage of 0.145 V with a current density of 0.05 A/m2 was obtained. The more voltage produced in case of nafion is attributed to its low resistance for hydrogen ion transport.
