    摘要: The disclosure relates to a fuel cell having a membrane electrode assembly installed in a cutout of a frame, a first bipolar plate arranged on a first side of the membrane electrode assembly and a second bipolar plate arranged on a second side of the membrane electrode assembly, the second side being opposite the first side. An edge region of the frame comprises a first elastomer layer on a first side of the edge region of the frame, the first side facing toward the first bipolar plate. The edge region of the frame further comprises a second elastomer layer on a second side of the edge region of the frame, the second side facing toward the second bipolar plate. The first and second elastomer layers are each formed as a film. The first and second elastomer layers are configured to fluidly seal the bipolar plates. A method for producing a fuel cell is also provided.

    摘要: A method of selecting a thermoplastic-resin adhesive provided so as to be exposed to a fluid flow path of a power generation cell includes a load application step, an exposing step, a measurement step, and a selecting step. In the load application step, a compressive load is applied to a laminate body in a laminating direction thereof, the laminate body being formed by sandwiching an adhesive between a first resin film and a second resin film. In the exposing step, the laminate body is exposed to an environment heated to a predetermined temperature and humidified to a predetermined humidity. In the measurement step, a flow amount of the adhesive during the exposing step is measured. In the selecting step, the adhesive having the flow amount equal to or less than a predetermined amount is selected as an adhesive used for the power generation cell.

    摘要: A bipolar plate for an electrochemical system, comprising a first separator plate and a second separator plate. The first and the second separator plate each comprising: at least two through-openings, an active region, and a distribution or collection region with structures for guiding a reaction medium between one of the through-openings and the active region. The structures for guiding the reaction medium in the distribution or collection region comprise flow channels for the respective reaction medium, said flow channels being separated from each other by webs. Adjacent to the first through-opening, the separator plates bear directly against each other in a contact plane. The distribution or collection region of the first separator plate and/or the distribution or collection region of the second separator plate have at least one compensating region.

    摘要: The present disclosure provides a separator-integrated gasket and a manufacturing method therefor, with which the likelihood of the gasket peeling away from the separator can be reduced while reducing the number of manufacturing steps. The separator-integrated gasket includes gaskets 210, 220 that are provided integrally with a separator 200 forming a fuel cell, wherein the separator 200 is formed from carbon to which a thermoplastic first resin material has been added, and the gaskets 210, 220 are formed from a thermoplastic second resin material that is compatible with the first resin material.
