FLUORINATION OF A POROUS HYDROCARBON-BASED POLYMER FOR USE AS COMPOSITE MEMBRANE

Fluorination of a porous hydrocarbon-based polymer for use as a composite membrane and, more particularly, for use as a composite proton exchange membrane for a fuel cell. The composite membrane is formed by fluorination of the porous hydrocarbon-based polymer to yield a selectively fluorinated poly...

Zusammenfassung:Fluorination of a porous hydrocarbon-based polymer for use as a composite membrane and, more particularly, for use as a composite proton exchange membrane for a fuel cell. The composite membrane is formed by fluorination of the porous hydrocarbon-based polymer to yield a selectively fluorinated polymer, which is then loaded with an ionomer to yield the composite membrane.
