    Abstract: A novel alkyl chain modified sulfonated polyether sulfone copolymer and a manufacturing method thereof are provided. The alkyl chain modified sulfonated polyether sulfone copolymer has high thermal stability and mechanical stability, is economic, and has low methanol penetration, excellent proton conductivity, and excellent water absorption, thereby being useful for the commercialization of fuel cells such as a polymer electrolyte membrane fuel cell or a direct methanol fuel cell by replacing conventional Nafion.
