  • Patent number: 7670709
    Abstract: The invention is drawn to a gasket (34) for use in an individual fuel cell (20). The gasket (34) includes at lest one generally rigid bridge (44) or (46) that extends across the fluid flow channels in adjacent separator plates (38) and (40). The bridge (44) or (46) assures that the fluid flow channels are not blocked or restricted in the cell (20). Each bridge (44) or (46) may be integral with its corresponding gasket (34). The gasket (34) may be a multi-piece gasket with a carrier material having an elastrometric seal portion (74) secured to it.

  • Patent number: 7147231
    Abstract: A gasket for statically sealing between two members is disclosed. The gasket includes a first generally planar portion having an inner perimeter and an exterior perimeter, and having a first surface and a second surface on an opposite side from the first surface. A seal bead rises from the first surface a first predetermined height and extends about the inner perimeter. A fastener hole extends through the first portion and is located between the seal bead and the exterior perimeter. The gasket also includes a protruding feature located between the fastener hole and the exterior perimeter that rises from the first surface a second predetermined height that is about equal to or greater than the first predetermined height.

  • Publication number: 20030013001
    Abstract: The present invention includes a fuel cell assembly. The fuel cell gasket preferably includes a gasket assembly, wherein the gasket assembly includes thin, flexible carrier having a first surface and a second surface. An elastomeric seal is molded onto the first surface of the carrier. Additionally, a second elastomeric seal is preferably molded onto the second surface of the carrier. Additionally, a pressure sensitive adhesive is preferably applied to the second surface of the carrier.

  • Patent number: 4680174
    Abstract: Cells such as genetically modified cells, e.g., hybridoma, which secrete an antigenic substance are encapsulated within capsule membranes having pores of dimensions sufficient to permit efflux of the antigens secreted by the cells but insufficient to permit traverse of the cells. The capsules are injected into an experimental animal where antigen passing through the pores of the capsule membrane induces lymphocytes to produce antibodies complementary to the antigen. The antibody may be harvested from the circulatory system of the animal. Preferably, lymphocytes are sampled from, e.g., the spleen of the animal, fused with a malignant cell line to produce a hybridoma which synthesizes the antibody in vivo, and the hybridoma is cultured to produce large quantities of monoclonal antibody.
