Polymer membrane for fuel cell, method of preparing the same, and stack for fuel cell and full cell system comprising the same

A porous support of this invention has a fuel cell polymer electrolyte membrane, a preparation method thereof and, more particularly, to the microporous membrane wherein an electrolyte polymer for fuel cells as a fuel cell stack and a fuel cell system including the same; Metal ion adsorbent material layer formed on the surface of the porous support; And a proton conductive polymer which is located inside the fine pores of the porous support, the metal ion adsorbent material layers. And can minimize the reduction in conductivity of hydrogen-ion conductive polymer by the metal ions generated by the corrosion of the metal separator film is a polymer electrolyte according to the present invention can also exhibit excellent life characteristics. Fuel cells, polymer electrolyte membrane, a metal separator, corrosion, metal complex.
