    摘要: A seal structure of a fuel cell includes an interrupted back-up disposed at least one of a connecting gas passage and a connecting coolant passage. The back-up located on one side of a separator and a portion of a seal line located on the other side of the separator are disposed such that the back-up and the portion of the seal line are overlapped with each other in a fuel cell stacking direction. The interrupted back-up may be formed in the seal or in the separator.

    摘要: A fuel cell module, wherein slopes of a same angle θ relative to a bottom face are formed on both side faces to form a recessed groove in a tapered shape. Since the angle θ is provided to the side faces of the recessed groove, the exhaustion of gases from the accumulation of gasses to the outside can be assisted by the side faces with the angle θ more than in a case where the side faces of the recessed groove are formed in right angled shapes even if the accumulation of gases is produced between an adhesive agent and the inner surfaces of the recessed groove when first and second separators are joined to each other for modularization by covering the first separator on the second separator. Thus, the accumulation of the gases can be prevented from occurring.

    摘要: In a fuel cell having a cell structure in which a gas flow passage is formed by an expanded metal, a bond portion connecting a mesh of the expanded metal stands partially upright in a position where a bond length is shortened so as to form a part of a strand portion. Hence, in an opening formed by the mesh of the expanded metal, a surface area on which front and rear openings overlap in a direction increases when seen from an direction. Thus, a sectional area of gas flow passages constituted by a continuum in the direction of the openings overlapping in the direction increases. As a result, a gas flow flows without making repeated narrow turns, leading to a reduction in gas pressure loss.

    摘要: An electrode structure 15 is received in a joint portion of frames 13, 14. A first gas diffusion layer 19 and a first gas passage forming member 21 are arranged on a first surface of the electrode structure 15. A second gas diffusion layer 20 and a second gas passage forming member 22 are formed on a second surface of the electrode structure 15. A separator 23 is joined with a surface of the frame 13 and a surface of the gas passage forming member 21. A separator 24 is joined with a surface of the frame 14 and a surface of the gas passage forming member 22. A water passage 28 is formed between a flat plate 25 of the gas passage forming member 22 and the separator 24. The water passage 28 has a depth set to a value smaller than depth of a gas passage T2 of the gas passage forming member 22. Generated water is introduced from the gas passage T2 of the gas passage forming member 22 to the water passage 28 through capillary action via communication holes 29. The generated water in the water passage 28 is moved to a downstream side of the water passage 28 by pressure caused by oxidization gas. This prevents corrosion of the cathode side electrode catalyst layer and improves durability of the anode side gas passage forming member. As a result, a fuel cell capable of preventing decrease of power generation is provided.

    摘要: A fuel cell is configured to comprise a power generation layer including an electrolyte membrane, an anode and a cathode, separators and a gas flow path layer provided between the power generation layer and the separator. The gas flow path layer is structured by a plurality of corrugated elements. Each corrugated element has a corrugated cross section where first convexes that are convex toward the separator and second convexes that are convex toward the power generation layer are alternately arranged. The plurality of corrugated elements are arranged, such that a top surface of the first convex in one corrugated element and a bottom surface of the second convex in an adjacent corrugated element cooperatively form an integral surface, and a plurality of through holes are formed between the respective adjacent corrugated elements. The plurality of corrugated elements include a corrugated element having positions of the first convexes and the second convexes shifted in a positive side of the first direction from those of an adjacent corrugated element, and a corrugated element having positions of the first convexes and the second convexes shifted in a negative side of the first direction from those of an adjacent corrugated element. The volume of a first reaction gas flow path, which is formed along the positions of the second convexes on a separator-side of the gas flow path layer, is less than the volume of a second reaction gas flow path, which is formed along the positions of the first convexes on a power generation layer-side of the gas flow path layer.
