A polymer electrolyte membrane is provided to ensure ion conductivity and ion exchange capacity by comprising a polymer having a crosslinked unit block and to improve mechanical property including tensile strength. A polymer electrolyte membrane comprises a polymer having a repeating unit of chemical formula 1 or a polymer having a repeating unit of chemical formula 2. In chemical formula 1, A is a unit block having an ion exchange group; B is a unit block having a reactive group; m, n, p and q are an integer of more than 1. In chemical formula 2, A is a unit block having an ion exchange group; B is a unit block having a reactive group; R is H or hydrocarbon; m, n, p and q are an integer of more than 1. |
