Abstract

This study optimized the H 3 PO 4 acid doping level (ADL) of polybenzimidazole (PBI) polymer electrolyte membranes using Taguchi method and characterized their ionic conductivity, contour plot and performed statistical regression analysis. Electrochemical impedance spectroscopic (EIS) analysis revealed that PBI copolymer-1 exposed better ionic conductivity among other membranes used. The maximum proton conductivity of PBI copolymer-1was recorded as 6.30 mS/cm at a doping temperature of 130 °C, doping time of 6 hours, and an operating temperature of 160 °C whereby, the optimum parameters were driven from the contour plot and signal to noise ratios effect of variable factors. The ionic conductivity showed differentiable dependency on the ADL and required high operating temperature for maximum conductivity. Therefore, the data recommends that the PBI copolymer-1 may be applicable as a proton exchange membrane for the high-temperature polymer electrolyte membranes fuel cell.
