  • Porous Nafion membrane and method for preparing the same
    Patent number: 10236527
    Abstract: Provided are a method for preparing a Nafion membrane having a through-pore free monolithic porous structure throughout the bulk of the membrane through a one-step process very easily and a Nafion membrane having a through-pore free monolithic porous structure obtained from the method. The Nafion membrane having such a porous structure may have an increased surface area, and thus may improve the membrane/catalyst interfacial area and transport characteristics.
    Type: Grant
