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.",
