摘要: A fuel gas passage, an oxygen-containing gas passage, and a coolant passage extend through a fuel cell stack. Each of the fuel gas passage and the oxygen-containing gas passage is formed by serially connecting passages between the first through third fuel cell modules. The fuel gas flows through the fuel gas passage, and the oxygen-containing gas flows through the oxygen-containing gas passage from the first fuel cell module toward the third fuel cell module. The coolant passage is formed by serially connecting passages between the first through third fuel modules. The coolant flows through the coolant passage from the third fuel cell module toward the first fuel cell module. The direction of the flow of the coolant is opposite to the direction of the flows of the fuel gas and the oxygen-containing gas.

摘要: A fuel cell stack is comprised of a plurality of power generating units which are stacked along the horizontal direction. A corrugated passage groove having a shape corresponding to the shape of the underside surface of a corrugated passage groove of a first fuel gas passage is formed in a surface of a first metal separator. A corrugated passage groove having a shape corresponding to the shape of the underside surface of a corrugated passage groove of a second oxidant gas passage is formed in a surface of a third metal separator. The corrugated passage grooves overlap one another to define a refrigerant passage. An oxidant gas inlet port and a fuel gas inlet port are provided in the upper portion of the power generating unit, and an oxidant gas outlet port and a fuel gas outlet port are provided in the lower portion of the power generating unit. A refrigerant inlet port and a refrigerant outlet port are formed in each of the left and right portions of the power generating unit.

摘要: There has been a problem that the cell units cannot bear the load exerted on the units while being stacked since a fuel cell stack including a refrigerant channel formed between cell units each having an even number of electrolyte/electrode structures (MEA) and metal separators which are alternated does not have any structure supporting the separators forming the refrigerant channel in a stacking direction. In order to solve the above problem, in each of a first power generating unit and a second power generating unit, projections formed at the buffer portions of the separators are disposed in the same positions in the stacking direction with the MEA interposed therebetween. Since between the first and second power generating units, the projections of the buffer portions are staggered, the projections of the first and second power generating units are thereby disposed in the same positions in the stacking direction.

摘要: A fuel cell includes a membrane electrode assembly and separators which are stacked. A fuel gas channel allows a fuel gas to flow along a surface of one of a pair of electrodes. An oxidant gas channel allows an oxidant gas to flow along a surface of another of a pair of electrodes. A channel width of the oxidant gas channel in a central portion of the oxidant gas channel in a channel width direction is larger than a channel width of the oxidant gas channel in both end portions of the oxidant gas channel in the channel width direction. A channel width of the fuel gas channel in a central portion of the fuel gas channel in a channel width direction is smaller than a channel width of the fuel gas channel in both end portions of the fuel gas channel in the channel width direction.

摘要: Disclosed is a fuel cell in which an electrolyte membrane-electrode structure is held between the first separator and a second separator. The electrolyte membrane-electrode structure comprises a solid polymer electrolyte membrane, a cathode-side electrode and an anode-side electrode. An end portion of the solid polymer electrolyte membrane projects outwardly beyond end portions of gas diffusion layers, and the both surfaces of the end portion of the solid polymer electrolyte membrane are held between the first protective film and a second protective film. The thickness of the first protective film is set to be thinner than the thickness of the second protective film.

摘要: A first separator to which a resin film is joined beforehand is set in a cavity formed between a lower die and an upper die of an injection molding machine. At the time of die locking by moving the upper die toward the lower die, in the case where the total thickness of the resin film and the first separator is larger than a predetermined dimension, the resin film is pressed by the lower die or the upper die, and thus, the resin film is deformed by compression within its elastic deformation range.
