摘要: Provided are an anion exchange resin being capable of producing an electrolyte membrane, a binder for forming an electrode catalyst layer and a battery electrode catalyst layer, which have improved electrical properties and chemical properties. For example, used is an anion exchange resin which has a hydrophobic unit being composed of bisphenol AF residues repeated via carbon-carbon bond and a hydrophilic unit being composed of hydrophilic groups repeated via carbon-carbon bond, in which the hydrophilic group is formed by connecting an anion exchange group to a fluorene backbone via a divalent saturated hydrocarbon group, and in which the hydrophobic unit and the hydrophilic unit are connected via carbon-carbon bond.

摘要: 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.-

摘要: A metallic separator for fuel cells having a metal plate, an electroconductive coating layer covering at least a surface in front and back surfaces of the metal plate which contacts a raw material and/or a reaction product, and an electroconductive channel-forming member disposed on a surface of the coating layer and forming a channel for the raw material and/or the reaction product and/or a channel for a cooling medium for cooling. A surface layer on the metal plate has a tensile residual stress within such a range that no stress-corrosion cracking occurs.
