## Abstract The sulfonated poly(ether ether ketone ketone)/phosphotungstic acid (SPEEKK/PWA) composite membranes were researched for proton exchange membranes. The effect of casting condition on the properties of membranes was studied in detail. The study showed that the casting condition has great

## Abstract New membranes were prepared and evaluated as polymer electrolytes for PEMFCs. Polymers with PSU in the main chain and βC(O)(CF~2~)~3~SO~3~H in the side chain (PSUβPSA) were synthesized by substitution of PSUβLi and SFBF, followed by treatment with aqueous potassium hydroxide then sulfur
Novel poly(arylene ether ketone) with fluorene pendants were synthesized and then sulfonated into a series of poly(arylene ether ketone)s with sulfonated fluorene pendants using chlorosulfonic acid. The sulfonated polymers were thereafter cast into membranes from their solutions. The properties of t
