| abstract | The electrolyte separator for a direct methanol fuel cell is characterized in that a sulfonate (SO 3 - Na + ) is introduced into a polyether - amide multiblock copolymer by N - substitution reaction and then the membrane is formed by using a hot press. Another method for producing an electrolyte membrane for a direct methanol fuel cell comprises: carrying a polyether-amide multiblock copolymer membrane in a 1M H 2 SO 4 solution at 50 to 70 ° C for 24 to 36 hours, washing the membrane several times, And drying in an oven. The present invention relates to an electrolyte membrane for a direct methanol fuel cell having an excellent hydrogen ion conductivity and enhanced methanol barrier property by introducing a sulfonic acid group into a polyether-amide multiblock copolymer having excellent mechanical strength and processability by N-substitution reaction . |
