A High Oxidization Stability Polymer Electrolyte Designed for Fuel Cell
Novel poly (arylene ether) s with sulfonic acid groups attached to pendent biphenyl rings were successfully synthesized. The sulfonation took place only on the pendent biphenyl rings due to the special designed molecular structure. The sulfonated polymers were very soluble in common organic solvents and can be readily cast into tough and smooth films. The membranes cast from the sulfonated polymers showed excellent stabilities resistance to both oxidation and hydrolysis, as evidenced by subjecting to both Fentons reagent test and immersion in boiling water.
