Abstract
The application discloses a kind of fuel cell proton exchange membrane and preparation method thereof, the proton exchange membrane is with composite fiber as framework, fluorine-containing sulfonic acid ionomer is filled in the inside and surface of framework;The composite fiber includes sulfonated aromatic polymer and carrier;The carrier is non-hydrophilic rigid polymer.The sulfonated aromatic polymer is one or two of sulfonated polyether ether ketone, sulfonated polyether ketone, sulfonated polyether sulfone;The carrier is one or more of polyvinylidene fluoride, polyether sulfone, polyimide, and the fluorine-containing sulfonic acid ionomer is perfluorosulfonic acid ionomer.The proton exchange membrane provided by the application has a significant advantage in low humidity conditions compared to traditional PTFE reinforced membrane.
