The objective of the research is to synthesize the diazonium N-(perfluoroalkyl) benzenesulfonimide (PFSI) zwitterionic polymers as electrolytes in polymer electrolyte membrane (PEM) fuel cells. The proposed diazonium PFSI zwitterionic polymers are expected to enhance the thermal and chemical stability, increase the proton conductivity of electrolytes, and improve the catalyst efficiency in electrodes for PEM fuel cells. Synthesis of the perfluorobenzoyl peroxide initiator, homoplymerization of perfluoro (3-oxapent-4-ene) sulfonyl fluoride and coupling reaction with 4-nitrobenzene sulfonyl amide have been carried out successfully in the lab. All the intermediate chemicals are characterized by 1H NMR, 19F NMR and IR.
