摘要： A separator for a fuel cell, to be disposed opposing to a membrane electrode assembly, is provided. The separator includes a separator central area portion opposing to a center area of the membrane electrode assembly that concerns generating power, an outer edge portion located in an outer edge of the separator central area portion, a rubber molded body made of rubber, the rubber molded body being formed in the outer edge portion by die-casting a die-casting rubber material using die, and an adhesive layer formed in the outer edge portion, for adhering the rubber molded body to the outer edge portion. The adhesive layer is formed over an adhesive layer area that includes and is larger than an area where the rubber molded body is die-casted in the outer edge portion. Thus, a disadvantage due to burrs which are generated when die-casting the rubber molded body can be reduced.

摘要： A fuel cell separator includes a separator main body having a first surface and a second surface, and a first seal member disposed on the first surface. When a region on the first surface of the separator main body corresponding to an electrode member disposed on the second surface is defined as a power generation region, and a region on the first surface of the separator main body corresponding to an in-cell seal member is defined as a seal region, a displacement/vibration reducing member made of polymer is disposed at a part of the seal region. The displacement/vibration reducing member includes multiple protrusions and a coupling portion. When viewed in plan view, an axis line connecting the centers of the figures of the adjacent protrusions does not coincide with a center line passing through the widthwise center of the coupling portion. The coupling portion has a gate cut mark.

摘要： A rubber gasket for a fuel cell is interposed between a first member and a second member stacked in the fuel cell. The fuel cell includes: a seat portion arranged on a surface of the first member; and a lip portion that includes a first hill portion projecting from the seat portion toward the second member and having a curved surface with a first curvature radius and a second hill portion projecting from the first hill portion toward the second member and having a curved surface with a second curvature radius smaller than the first curvature radius, and that makes elastic contact with the second member. The seat portion includes a planar inclined surface inclined with respect to the surface direction at a connecting portion leading to a bottom of the first hill portion.

摘要： Provided is a method for manufacturing a gasket member as described below. A plate-like base material is clamped between a first and a second split mold, and a gasket is fixed to a surface of the base material by injecting and filling a rubber-like elastic material into a cavity defined between the base material and the first split mold. An air vent is provided including an exhaust groove and an exhaust hole, the exhaust groove extending from the cavity toward an inner or outer peripheral side on a butting surface between the base material and the first split mold and partially opening in a circumferential direction of the cavity, the exhaust hole extending from the exhaust groove in a clamping direction of the first and second split molds. Air in the cavity is discharged through the air vent when the rubber-like elastic material is injected and filled into the cavity.

When a compressive deformation ratio is defined as a ratio of a deformation amount in a height direction to pressure applied to the gasket in the height direction, in the first sealing part, the compressive deformation ratio at a section to be arranged on a first fuel cell side is greater than the compressive deformation ratio at a section to be arranged on a second fuel cell side, and in the second sealing part, the compressive deformation ratio at a section to be arranged on the second fuel cell side is greater than the compressive deformation ratio at a section to be arranged on the first fuel cell side.

摘要： A sealing part has an outer peripheral point of the sealing part within a range from 0 degree to 90 degrees around a center point of the sealing part relative to a stacking direction, and that is located at a distance of a first length L1 from the center point. Each point on the outer peripheral line within a first range satisfies L2≤L1, where L2 is a second length that is a distance from the center point to that point. Each point on the outer peripheral line within a second range satisfies L3

摘要： A fuel cell includes a power generating body including a membrane electrode assembly, a resin frame placed around the power generating body, and a pair of separators laminated on the resin frame so as to sandwich the power generating body and the resin frame. The resin frame has a resin-frame-side manifold in which reaction gas flows in a direction passing through the resin frame, an opening that holds the power generating body, and a gas introduction channel formed through the resin frame between the resin-frame-side manifold and the opening. Each separator has a separator-side manifold through which the reaction gas flows, and which is provided at a position corresponding to the resin-frame-side manifold in a lamination direction, and the gas introduction channel has a gas introduction part that extends into the separator-side manifold, when viewed in the lamination direction.
