Abstract
An organic/inorganic hybrid composite proton exchange membrane is provided. The proton exchange membrane includes an inorganic material of about 0.5-30 parts by weight and an organic material of about 99.5-70 parts by weight per 100 parts by weight of the proton exchange membrane. A surface area of the inorganic material is about 50-3000 m2/g. The organic material includes a sulfonated polymer or a phosphoric acid doped polymer.
Claims3
An organic/inorganic hybrid composite proton exchange membrane, comprising:
- an inorganic material of about 0.5 to 30 parts by weight per 100 parts by weight of the proton exchange membrane, wherein a surface area of the inorganic material is about 50 to 3000 m2/g, and wherein a material of the inorganic material comprises an unmodified carbon material, wherein the unmodified carbon material is an activate carbon or a mesoporous carbon material;
- and
- an organic material of about 99.5 to 70 parts by weight per 100 parts by weight of the proton exchange membrane, the organic material comprising a sulfonated polymer or a phosphoric acid doped polymer.
