Abstract:
1. A proton exchange membrane composition, comprising: a hyper-branched polymer, wherein the hyper-branched polymer has a degree of branching of more than 0.5; and a polymer with ion conductivity distributed uniformly over the hyper-branched polymer, wherein the polymer with ion conductivity comprises Nafion, sulfonated poly(ether ether ketone) (s-PEEK), sulfonated polyimides (s-PI), phosphoric acid/polybenzimidazole polymer (p-PBI), sulfonated poly(phenylene oxide) (s-PPO), sulfonated poly(arylene ether sulfone) (s-PES), or sulfonated poly(4-phenoxybenzoyl-1,4-phenylene) (S-PPBP), and wherein the hyper-branched polymer has a weight ratio equal to or more than 5 wt %, based on a solid content of the proton exchange membrane composition.
