Disclosed is a polymer electrolyte fuel cell including improved separators that cause no mixing of a fuel gas and an oxidant gas. The polymer electrolyte fuel cell comprises a plurality of membrane electrode assemblies and a plurality of conductive separators, wherein the plurality of conductive separators comprise at least one separator comprising: a fuel gas inlet-side manifold aperture; a fuel gas outlet-side manifold aperture; a gas flow channel for fuel gas formed on an anode-side of the separator; an inlet-side through hole and an outlet-side through hole penetrating the separator which are formed at an inlet-side end and an outlet-side end of the gas flow channel for fuel gas; and an inlet-side connection groove and an outlet-side connection groove for connecting the inlet-side and outlet-side through holes with the fuel gas inlet-side manifold aperture and the fuel gas outlet-side manifold aperture, respectively, which are formed on a cathode-side of the separator.
A polymer electrolyte fuel cell comprising:
A conductive separator for a polymer electrolyte fuel cell, comprising:
A conductive separator for a polymer electrolyte fuel cell, comprising a combination of two separator members consisting of an anode-side separator member and a cathode-side separator member, each separator member comprising a fuel gas inlet-side manifold aperture, a fuel gas outlet-side manifold aperture, an oxidant gas inlet-side manifold aperture, an oxidant gas outlet-side manifold aperture, a cooling water inlet-side manifold aperture, and a cooling water outlet-side manifold aperture, said two separator members being combined in such a manner that their backsides are in contact with each other,
