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.

Proton exchange membrane composition

The disclosed forms a proton exchange membrane. First, multi-maleimide and barbituric acid are copolymerized to form a hyper-branched polymer. Next, the solvent of the sulfonated tetrafluoroethylene copolymer (Nafion) aqueous solution is replaced from water with dimethyl acetamide (DMAc). 10 to 20 parts by weight of the hyper-branched polymer is added to the 90 to 80 parts by weight of the Nafion in a DMAc solution, stood and heated to 50&#xb0; C. to inter-penetrate the hyper-branched polymer and the Nafion. The heated solution is coated on a substrate, baked, and pre-treated to remove residue solvent for completing an inter-penetrated proton exchange membrane.

Inter-penetrated proton exchange membrane, method for manufacturing the same, and proton exchange membrane fuel cell utilizing the same

Disclosed is a gel electrolyte for a photosensitive dye and method for manufacturing the same. First, bismaleimide and barbituric acid are dissolved in Br&#xf6;nsted base solution to form a gelling additive. Subsequently, the gelling additive is added into an ionic liquid electrolyte. The liquid electrolyte is then gelled at room temperature to form a gel electrolyte for the photosensitive dye utilized in dye sensitized solar cells. In addition, barbituric acid is further added into the gelling additive to enhance the gelling rate of the ionic liquid electrolyte.

A proton exchange membrane and method for formation the same is disclosed. When forming the proton exchange membrane, first, a bismaleimide and barbituric acid are copolymerized to form a hyper-branched polymer. Next, the solvent of the sulfonated tetrafluorethylene copolymer (Nafion) aqueous solution is replaced with dimethyl acetamide (DMAc). 10 to 15 parts by weight of the hyper-branched polymer is added to 90 to 85 parts by weight of the Nafion in the DMAc solution, stood and heated to 50&#xb0; C. for inter-penetration of the hyper-branched polymer and the Nafion. The heated solution is coated on a substrate, baked, and pre-treated to remove residue solvent to complete formation of the proton exchange membrane.
