Abstract

The invention discloses a polymer intercalation zirconium phosphate proton exchange membrane. The polymer intercalation zirconium phosphate proton exchange membrane is prepared from the following rawmaterials in parts by weight: 30-40 parts of phosphoric acid solution with the concentration of 96-98%, 20-22 parts of zircon, 10-15 parts of acrylamide, 0.3-0.4 parts of initiator, 110-120 parts of modified polyphenyl ether, 2-3 parts of lauryl dimethyl amine oxide, 0.4-1 parts of 8-hydroxyquinoline, and 1-2 parts of aminopropyl triethoxysilane. By virtue of alloying of the amino-intercalation solution and oleic acid-doped antioxidant polyphenyl ether, and through a reaction between amino and oleic acid, effective compatibility between intercalation zirconium phosphate and polyphenyl ether isrealized, thereby improving uniform stability and mechanical strength of the finished proton membrane.

Description

technical field [0001] The invention belongs to the field of proton membranes, in particular to a polymer-intercalated zirconium phosphate proton exchange membrane and a preparation method thereof. Background technique [0002] The proton exchange membrane is the core component of PEMFC, and PEM is different from the diaphragm used in general chemical power sources. Proton exchange membrane fuel cells have become the most competitive clean alternative power source for gasoline internal combustion engines. The materials used as PEM should meet the following conditions: good proton conductivity, small electroosmosis of water molecules in the membrane, and gas in the membrane. The permeability in the medium is as small as possible, the electrochemical stability is good, the dry-wet conversion performance is good, it has certain mechanical strength, good processability, and the price is reasonable; the proton exchange membrane fuel cell has become the most competitive clean fuel...
