NOVELTY - An anion exchange resin comprises a bivalent hydrophobic group consisting of several aromatic rings mutually coupled through a bivalent saturated hydrocarbon group, bivalent bonding group consisting of several aromatic rings consisting of a single aromatic ring and mutually coupled through a carbon-carbon bond, and bivalent hydrophilic group coupled with aromatic rings through a bivalent saturated hydrocarbon group having anion exchange group coupled through the carbon-carbon bond.    USE - Anion exchange resin for electrolyte layer and binder for electrode catalyst layer of fuel cell (all claimed) e.g. solid polymer electrolyte fuel cell, molten carbonate-type fuel cell, solid electrolyte-type fuel cell and phosphoric acid-type fuel cell for motor vehicles, boats and ships, aircraft and communication terminals e.g. mobile telephone.    ADVANTAGE - The anion exchange resin has excellent alkali resistance, and provides fuel cell having excellent durability.    DETAILED DESCRIPTION - An anion exchange resin comprises a bivalent hydrophobic group consisting of several aromatic rings mutually coupled through a bivalent saturated hydrocarbon group, bivalent bonding group consisting of several aromatic rings consisting of a single aromatic ring and mutually coupled through a carbon-carbon bond, and bivalent hydrophilic group coupled with aromatic rings through a bivalent saturated hydrocarbon group having anion exchange group coupled through the carbon-carbon bond. The hydrophobic group and bonding group are repeated through an ether bond. The hydrophilic group and the bonding group are repeated through an ether bond. The hydrophobic unit and hydrophilic unit are bonded through the ether bond. An INDEPENDENT CLAIM is included for fuel cell (1) having fuel cell electrode (2) and oxygen side electrode (3) opposingly arranged on both sides of electrolyte layer (4) containing the anion exchange resin. The fuel is hydrogen-containing liquid fuel.    DESCRIPTION OF DRAWING(S) - The drawing shows the schematic block diagram of fuel cell.
