<p>PURPOSE: An intramolecular ionic cross-linkable copolymer, a producing method of a polymer electrolyte membrane using thereof, and a fuel cell including thereof are provided to improve the durability, to maintain the ion conductivity level for a conventional polymer electrolyte membrane, and to obtain a low water absorbing ability. CONSTITUTION: An intramolecular ionic cross-linkable poly(arylene ether sulfone) copolymer includes a structure marked as chemical formula 1. In the chemical formula 1, R refers to an element selected from -S-, -SO2-, -C=O-, and their combination. R' is a direct coupling -O-, -SO2-, -C=O-, or -C(CH3)2-. X refers to a leaving group which includes a halogen atom with F, Cl, and Br, or a nitro group.</p> |
