## Abstract Sulfonated poly(aryl ether) (SPAE) and sulfonated poly(fluorenyl ether ketone) (SPFEK) are synthesized by post‐sulfonation and direct polymerization from the sulfonated monomer, respectively. Flexible and smooth proton exchange membranes (PEM) are readily obtained from both polymers, by
