Abstract
Proton exchange membrane compositions having high proton conductivity are provided. The proton exchange membrane composition includes a hyper-branched polymer, wherein the hyper-branched polymer has a DB (degree of branching) of more than 0.5. A polymer with high ion conductivity is distributed uniformly over the hyper-branched polymer, wherein the hyper-branched polymer has a weight ratio equal to or more than 5 wt %, based on the solid content of the proton exchange membrane composition.
