Polymer membrane for fuel cell, method of preparing same, and membrane-electrode assembly for fuel cell comprising same |
| abstract |
The polymer electrolyte membrane of the present invention includes polymers having a fluoroalkyl group and a proton conductive group. The present invention also provides a membrane-electrode assembly, a fuel cell system including the polymer electrolyte membrane, and a method of making the polymer electrolyte membrane by a chemical grafting method. The amount of the proton conductive groups in the polymer electrolyte membrane can be controlled, the membrane thickness can be easily controlled, adherence between a polymer electrolyte membrane and an electrode is improved due to the fluoroalkyl of the polymer, and long-term stability of a membrane-electrode assembly is improved. |
