Abstract
The present invention relates to an ion conductor, a method for producing the same, and an ion exchange membrane, a polymer electrolyte membrane and a fuel cell including the same. The ion conductor includes a repeat unit represented by the following Formula 1, and a repeat unit represented by the following Formula 2 or a repeat unit represented by the following Formula 5. Formulae 1, 2 and 3 are described as in the Detailed Description of the Invention. The ion conductor contains a hydrocarbon-based block copolymer which has an easily changeable structure because it includes a hydrophilic region and a hydrophobic region, wherein characteristics of the block copolymer and the ion conductor can be easily regulated through control over the structure of the hydrophilic region and the hydrophobic region, and ion conductivity and durability of the ion conductor are improved within the whole humidity range through micro-phase separation between the hydrophilic region and the hydrophobic region which are structurally controlled.
