摘要:
Provided are a tri-block copolymer and an electrolyte membrane prepared therefrom. The tri-block copolymer has a structure of polar moiety-containing copolymer block / non-polar moiety-containing copolymer block / polar moiety-containing copolymer block, or non-polar moiety-containing copolymer block / polar moiety-containing copolymer block / non-polar moiety-containing copolymer block, and is useful for an electrolyte membrane for fuel cells. The electrolyte membrane for fuel cells prepared from the tri-block copolymer exhibits superior dimensional stability and excellent fuel cell performance.
摘要:
Provided are a polymer electrolyte membrane for fuel cells, and a membrane electrode assembly and a fuel cell including the same. More specifically, provided is a polymer electrolyte membrane for fuel cells including a hydrocarbon-based cation exchange resin having hydrogen ion conductivity and fibrous nanoparticles having a hydrophilic group. By using the fibrous nanoparticles having a hydrophilic group in conjunction with the hydrocarbon-based cation exchange resin having hydrogen ion conductivity, it is possible to obtain a polymer electrolyte membrane for fuel cells that exhibits improved gas barrier properties and long-term resistance, without causing deterioration in performance of fuel cells, and a fuel cell including the polymer electrolyte membrane.
