Abstract

The invention provides an imidazole side chain type anion exchange membrane for a fuel cell and a preparation method thereof, belonging to the fields of polymer chemistry and anion exchange membrane fuel cells. The anion exchange membrane is different according to the molar ratio of monomers: the molar ratio of methyl hydroquinone monomer to allyl bisphenol S monomer is: a:b (a, b are integers from 1 to 9 and a+b=10 ); the present invention also provides a preparation method of an imidazole side chain type anion exchange membrane, which is to utilize nucleophilic polycondensation reaction to polymerize in different molar ratios of monomers to form a first-grade hydroquinone-containing monomer and an allyl-containing bis Poly(aryletherketone sulfone) with different proportions of phenol S monomer was used to prepare an anion exchange membrane with imidazole side chains. The ion conductivity of the imidazole side chain type anion exchange membrane at 80 DEG C can reach up to 0.157 S / cm.

Description

Imidazole side chain type anion exchange membrane for fuel cell and preparation method thereof technical field The invention belongs to the field of polymer chemistry and anion exchange membrane fuel cells, in particular to a kind of fuel cell Imidazole side chain type anion exchange membrane and preparation method thereof. Background technique In recent years, in order to pursue rapid economic development, people use fossil energy excessively, causing energy exhaustion and environmental pollution. At this time, as a new type of renewable energy, fuel cells have gradually entered the attention of researchers from all over the world. Currently, Most of the research focuses on the field of proton exchange membrane fuel cell, but because its catalyst needs to use expensive gold. genus, which greatly limits the promotion and development of proton exchange membrane fuel cells. In contrast, anion exchange membrane fuel cells have It has the advantages of fast fuel oxid...
