Abstract
Binder composites for membrane electrode assemblies and membrane electrode assemblies employing the same are provided. The binder composition includes a solvent, a hyper-branched polymer and a polymer with high ion conductivity, wherein the hyper-branched polymer and the polymer with high conductivity of hydronium are distributed uniformly over the solvent, and the hyper-branched polymer has a DB (degree of branching) of more than 0.5.
