Fluorine‐free proton exchange membranes are increasingly required to replace perfluoro sulfonic acid (PFAS) materials in hydrogen fuel cells operating at low humidity and moderate temperatures. In this work, a one‐step grafting–crosslinking strategy was used to fabricate a dual‐functionalized sulfonated poly(ether sulfone) membrane (SPESOD) incorporating hydrophobic octylamine side chains and sulfonamide crosslinks via NH2PES.
