  • Patent number: 10626993
    Abstract: The present invention improves the handling properties of a rubber-only gasket and the affixability thereof to an attachment position. To this end, the provided gasket is: obtained by combining a gasket body of the rubber-only type, and a carrier sheet that comprises a resin film and holds the gasket body in an un-adhered state; and characterized in that the gasket body is provided with an adhesive section or bonding section for adhering or bonding the gasket body to an attachment position when attaching the gasket body to the attachment position. The adhesive section or bonding section is prepared by providing the lateral surface of the gasket body with a projecting section, and coating the surface of the projecting section with an adhesive or bonding agent. The gasket body is to be used as a gasket for a fuel cell to be incorporated into a fuel cell stack.

  • Patent number: 10465798
    Abstract: The invention provides a gasket which improves a handling workability of a rubber only type gasket. The gasket of the invention is constructed by a combination of a rubber only type gasket main body, and a carrier sheet which is made of a resin film retaining the gasket main body in a non-bonded state, and the carrier sheet is provided with an air inflow port for making air flow into a portion between the carrier sheet and the gasket main body when the gasket main body is detached from the carrier sheet. A gasket retention portion having a three-dimensional shape which is deformed along an outer shape of the gasket main body is arranged at a position which laps over the gasket main body in a plane in the carrier sheet, and the gasket main body is partly accommodated within the gasket retention portion in a thickness direction.

  • Publication number: 20190257426
    Abstract: A gasket includes a reinforcing body made of a resin film, a one-side gasket body on one surface of the reinforcing body, and another-side gasket body on another surface of the reinforcing body. The reinforcing body has, between both gasket bodies, a three-dimensional shape in which the resin film is bent. The one-side gasket body includes an inversely-tapered engaging convex portion protruding toward the other-side gasket body, the reinforcing body includes a deformation portion as the three-dimensional shape deforming along a shape of the engaging convex portion, and the other-side gasket body includes an inversely-tapered engaging concave portion embedding therein the engaging convex portion and the deformation portion. At least one of the one-side gasket body and the other-side gasket body includes a flat surface-shaped seal surface, and the reinforcing body has a convex shape as the three-dimensional shape protruding toward the flat surface-shaped seal surface.

  • Patent number: 10350799
    Abstract: The purpose of this invention is to make it easy to handle all-rubber gaskets. To achieve this purpose, a gasket is characterized in that a gasket body of only rubber is combined with a carrier film that is made from a resin film to hold the gasket body in a non-adhesive state. A three-dimensional portion having a shape that is deformed along the external shape of the gasket body is provided at a position where the gasket body and a plane of the carrier film overlap, and a portion of the gasket body is contained in the three-dimensional section. The gasket body is used as a gasket for fuel cells incorporated into a fuel cell stack.
