Abstract

The effect of crosslinking by a hydrophilic group on a sulfonated polyimide electrolyte membrane fuel cell, was investigated. The sulfonated polyimides end-capped with maleic anhydride were self-crosslinked with poly(ethylene glycol) diacrylate. It was observed that thermal stability was good for all the sulfonated polyimides that exhibited a three-step degradation pattern. The results show that the proton conductivity of the crosslinked sulfonated polyimides with poly(ethylene glycol) diacrylate increased with the increase in poly(ethylene glycol) diacrylate despite the fact that the ion exchange capacity was decreased.
