Proton exchange membranes (PEMs) were prepared with varying molecular weight (M.W.) of polyethylene glycol (PEG) (200/1500/6000) along with polyvinyl alcohol (PVA), orthophosphoric acid (OPA) and chitosan (CS) by physical blending and casting method. Ion exchange capacity (IEC) and water uptake of the membranes were found to decrease with increasing the molecular weight of PEG. The maximum power density, current density, an opencircuit voltage (OCV) were5.28 mW/m 2 , 3.88 mA/m 2 and 0.74 V observed in cylindrical shape microbial fuel cells (CYMFCs). While the power density, current density, and open-circuit voltage (OCV) of rectangular shape microbial fuel cells (REMFCs) were 61.93 mW/m 2 , 106.48 mA/m 2 and 1 V, respectively. In this work, we have optimized the molecular weight of PEG in the synthesized of PEMs and compared the performances of prepared membranes in two different designs of MFCs. The rectangular shape MFCs performed better compared to cylindrical shape MFCs.
