Abstract

Poly(methyl methacrylate-co-nitrophenyl maleimide) (P(MMA-co-NMI)) and poly(methyl methacrylate-co-hydroxyphenyl maleimide) (P(MMA-co-HMI)) Copolymers were synthesized using free radical polymerization reaction. proton exchange membranes fuel cell (PEMFC) by dry-phase inversion method were fabricated using different concentrations of these Copolymers and Phosphotungstic acid (PWA) as an additive of the proton conductive agent. To identify and investigate were used FT-IR, IEC, Wu, SEM, TGA, DSC, and DTG and proton conductivity (Impedance Spectroscopy) methods. Results revealed applying (P(MMA-co-HMI)) and PWA significantly improved the proton conductivity of membrane (2. 6×10− 1 S. cm− 1) due to improving the interaction between the functional groups of PWA (H3O+ ions, O atoms) and MMA-co-HMI Copolymer (OH, C=O functional groups).
