Abstract: The present invention provides an anion exchange resin capable of producing an electrolyte membrane for a fuel cell, a binder for forming an electrode catalyst layer and a battery electrode catalyst layer. The anion exchange resin of the present invention has a hydrophobic unit, a hydrophilic unit and divalent fluorine-containing groups. The hydrophobic unit has divalent hydrophobic groups composed of one aromatic ring or a plurality of aromatic rings that are repeated via carbon-carbon bond. The hydrophilic unit has divalent hydrophilic groups composed of one aromatic ring or a plurality of aromatic rings, at least one of which has an anion exchange group, that are repeated via carbon-carbon bond. The divalent fluorine-containing groups have a specific structure and are bonded via carbon-carbon bond to the hydrophobic unit and/or the hydrophilic unit and/or a moiety other than these units.

Abstract: Provided are an anion exchange resin being capable of producing an electrolyte membrane for a fuel cell, a binder for forming an electrode catalyst layer and a fuel cell electrode catalyst layer, which have an improved physical property (anion conductivity); a method for producing thereof; an electrolyte membrane for a fuel cell, a binder for forming an electrode catalyst layer and a fuel cell electrode catalyst layer produced from the anion exchange resin; and a fuel cell having the electrolyte membrane or the electrode catalyst layer.For example, the anion exchange resin is obtained by reacting a hydrophobic monomer with an aminoalkyl group-containing monomer, in which the hydrophobic monomer is composed of one aromatic ring or a plurality of aromatic rings to which two halogen atoms are bonded, and the aminoalkyl group-containing monomer is composed of one aromatic ring or a plurality of aromatic rings to which two halogen atoms are bonded and an aminoalkyl group is introduced; and by quaternizing the amino group. In the anion exchange resin, a divalent hydrophobic group formed by the residue of the hydrophobic monomer, and a divalent hydrophilic group formed by the residue of the quaternized aminoalkyl group-containing monomer are bonded via direct bond.
