The present invention relates to a copolymer for preparing a membrane of a fuel cell, a method for preparing the same, and a fuel cell. The purpose of the present invention is to provide a membrane having thermal/mechanical stability, excellent ion exchange capacity, and ion conductivity. The copolymer for preparing a membrane of a fuel cell contains a hydrophobic portion represented by chemical formula 1 and a hydrophilic portion represented by chemical formula 2, wherein the hydrophobic portion and the hydrophilic portion are block-copolymerized. In chemical formulas 1 and 2, Q1 and Q2 each are independently a single bond, -CH_2-, or -C(R1)(R2)-; x and y each are independently an integer of 1 or greater; R1 and R2 each are independently an alkyl group having one to three carbon atoms; and M1 is a monovalent cation. |
