Abstract: PURPOSE: Provided is a method for making an electrolyte membrane for a fuel cell, which uses polyimide having excellent thermal, chemical and mechanical properties to give a polymeric electrolyte membrane having excellent chemical resistance, heat resistance and heat stress resistance, and high ion-conductivity. CONSTITUTION: The method comprises the step of forming a copolymerized sulfonated polyamic acid(polyimide precursor) by dissolving two different diamines at 30 deg.C under nitrogen atmosphere and mixing thereto a dianhydride. Additionally, a crosslinked type copolymerized sulfonated polyamic acid is formed by a two-step condensation. Both of the sulfonated polyamic acid solutions are directly used to form an electrolyte membrane. Otherwise, the copolymerized sulfonated polyamic acid, the crosslinked type copolymerized sulfonated polyamic acid and an inorganic additive are used to form an organic/inorganic composite electrolyte membrane.
