Abstract
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
