<p>A semi-crosslinked polymer membrane is provided to ensure excellent heat resistance, chemical resistance, mechanical property, and hydrolytic stability and to effectively block a methanol crossover phenomenon while not affecting the hydrogen ion conductivity. A semi-crosslinked polymer membrane comprises a blend of a sulfonated polyimide copolymer indicated as the chemical formula 1 and polyethylene glycol diacrylate. The content of the polyethylene glycolarylate is 10~50 weight% based on the total weight of blend.</p> |
