Abstract: A polymer electrolyte membrane, a method for manufacturing the same, and a membrane electrode assembly containing the polymer electrolyte membrane are disclsosed. 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.

Abstract: The present invention relates to an ion exchange membrane, a method for manufacturing the same, and an energy storage device including the same, and the ion exchange membrane includes a porous support including a plurality of pores and an ion conductor filling the pores of the porous support, in which the porous support includes micropores having a size of 31 to 1000 μm. The ion exchange membrane may achieve high energy efficiency in the case of being applied to an energy storage device such as a vanadium redox inflow battery due to high charge/discharge cycle durability, high ion-conductivity, and excellent chemical and thermal stability.

Abstract: Disclosed are a polymer electrolyte membrane, a method of manufacturing the membrane, and a membrane-electrode assembly including the membrane. The polymer electrolyte membrane contains a porous support having a plurality of pores, a first layer including a first ion conductor that fills the pores adjoining one surface of the porous support, and a second layer including a second ion conductor that fills the pores adjoining the other surface of the porous support, wherein the first ion conductor and the second ion conductor are different from each other, and one selected from the group consisting of the first layer, the second layer, and a combination thereof includes an organic-based antioxidant.
