使用基于直接荧光的表面处理技术的膜交换聚合物膜，膜电极组件和包含其的燃料电池

PROTON EXCHANGE POLYMER MEMBRANE USING SURFACE TREATMENT TECHNIQUE BASED ON DIRECT FLUORINATION, MEMBRANE-ELECTRODE ASSEMBLY, AND FUEL CELL COMPRISING THE SAME
摘要：
A proton exchange polymer membrane whose surface is treated by direct fluorination using a fluorine gas, a membrane-electrode assembly, and a fuel cell comprising the same are provided. The proton exchange polymer membrane of the present invention exhibits improved proton conductivity, high dimensional stability, and decreased methanol permeability through introducing hydrophobic fluorine having high electronegativity to the surface of the polymer membrane. Therefore, the proton exchange polymer membrane with excellent electrochemical properties of the present invention can be preferably utilized as polymer electrolyte membrane for fuel cell, generating electric energy from chemical energy of fuels.
摘要（中）：

提供了通过使用氟气直接氟化处理其表面的质子交换聚合物膜，膜电极组件和包含该质子交换聚合物膜的燃料电池。 本发明的质子交换聚合物膜通过将具有高电负性的疏水性氟引入聚合物膜的表面，显示出改进的质子传导性，高尺寸稳定性和降低的甲醇渗透性。 因此，本发明的具有优异的电化学特性的质子交换聚合物膜可以优选用作燃料电池的聚合物电解质膜，从燃料的化学能产生电能。
