Method for manufacturing polymer electrolyte membrane, and electrolyte membrane manufactured by same

Abstract

The present disclosure relates to a method for manufacturing a polymer electrolyte membrane, the method comprising the steps of (a) preparing a porous support containing a plurality of pores, (b) preparing an ion conductor dispersion solution by dispersing an ion conductor in a dispersion medium, (c) contacting the dispersion medium with the porous support to wet the dispersion medium on the porous support, and (d) introducing the ion conductor to at least one surface of the porous support by applying the ion conductor dispersion solution to the porous support wetted with the dispersion medium, and a polymer electrolyte membrane manufactured thereby.
