Abstract

The invention provides a graphene oxide polymer composite proton exchange membrane, a preparation method thereof and application. The composite proton exchange membrane comprises graphene oxide and polymer resin; the graphene oxide is adenosine triphosphate modified graphene oxide; the mass percentage of the graphene oxide in the composite proton exchange membrane is 0.1-15%; the mass percentage of the polymer resin in the composite proton exchange membrane is 85-99.9%. The graphene oxide orderly distributed in the composite proton exchange membrane provided by the invention constructs a proton transmission channel with long-range continuity; strong interaction is generated between phosphate groups and between the phosphate groups and sulfonic acid groups in the graphene oxide channel, sothat rich proton transfer sites are provided for the composite proton exchange membrane, and the improvement of proton conduction performance is promoted; the graphene oxide is of a layered arrangement structure and effectively serves as a barrier layer of methanol molecules, so that the permeation rate of fuel is reduced, and the selectivity of the proton exchange membrane is improved.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a graphene oxide / polymer resin composite proton exchange membrane and its preparation method and application. Background technique [0002] Direct methanol fuel cell (DMFC) is a new type of energy conversion device that directly converts the chemical energy of methanol into electrical energy. It has attracted extensive attention due to its advantages of high energy density, fast start-up, low pollution and compact design. Proton exchange membrane (PEM) is the core component of the membrane electrode in DMFC. Its function is mainly to isolate fuel and oxidant, isolate electrons, specifically conduct protons, and directly determine the operating performance of the battery. At present, the most widely commercialized proton exchange membrane is perfluorosulfonic acid proton exchange membrane, and the most common perfluorosulfonic acid proton exchange membrane is Nafion membrane; N...
