Abstract: In present study, different blend compositions of polybenzimidazole (PBI) and polyvinylpyrrolidone (PVP) have been analyzed as polymer electrolyte membrane in single chambered MFCs. Four membranes namely, pure PBI, PBI/PVP 70:30, 50:50, and 30:70 blend ratios with increasing PVP content were casted, where the hygroscopic properties of the membranes were found enhanced with increasing PVP content. The membranes were characterized at room temperature (22 + 2 °C) with different ion exchange (IEC) and proton conductive capacities, where an IEC of 0.06 meq g-1, 0.15 meq g-1, 0.24 meq g-1 and 0.36 meq g-1 and proton conductivity of 2.5 × 10-4, 4.8 × 10-4, 9.36 × 10-4 and 1.2 × 10-3 S cm-1 were observed from pure PBI, PBI/PVP 70:30, 50:50, and 30:70 membranes respectively. As membrane electrode assemblies (MEA), the casted membranes were sandwiched in-between carbon cloths, where a maximum power and current density of 231.38 ± 12 mW m-2 and 1242 ± 62 mA m-2 were observed from 30:70 PBI/PVP fitted MFC, using mixed firmicutes as biocatalysts. A gross 84.36% COD removal from 30:70 PBI/PVP membrane indicated the added effect of PVP in blend composition with approximately 81% higher power over pure PBI membrane. The results indicate the potential efficacy of PBI/PVP blends as seperators in microbial fuel cell, for bio-energy conversion over pure PBI membrane. © 2016 Published by Elsevier B.V.
