Abstract
A polymer electrolyte membrane, a method for manufacturing the same, and a membrane electrode assembly containing the polymer electrolyte membrane are disclosed. The polymer electrolyte membrane includes: a fluorine-based support containing a plurality of pores due to polymer microfibrillar structures; a hybrid porous support placed on one side or both surfaces of the fluorine-based support and comprising nanowebs obtained by integrating nanofibers into a nonwoven fabric containing a plurality of pores; and ion conductors with which the pores of the porous support are filled. The polymer electrolyte membrane can reduce hydrogen permeability while being excellent in both durability and ion conductivity.
