The performance and stability of sulfonated polytriazoles with polymer backbones containing diphenyl ether (S‐DPE‐PT) and hexafluorisopropylidene groups (S‐FPT) were compared, aiming their application as proton conductive membranes for fuel cell. The chemical stability of both membranes were compared and analyzed by infrared spectroscopy after 24 h heating at temperatures up to 250 °C. The superior stability of the fluorinated polytriazole was confirmed. Copyright © 2009 Curtin University of Technology and John Wiley & Sons, Ltd.
