Abstract: 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.

Abstract: A method for producing a membrane electrode assembly for a fuel cell includes providing a first component of the membrane electrode assembly as part of a continuous material web which passes through a plurality of processing stations and connecting a second component of the membrane electrode assembly to the first component by a firmly bonded connection.

Abstract: A single cell for a fuel cell stack is provided, having a membrane electrode assembly arranged in an active region, being associated with at least one single plate, which is formed with a flow field to supply an operating medium to the active region of the membrane electrode assembly, which is fluidically connected to a media port present on the side away from the active region. Lateral with respect to the membrane electrode assembly there is a lamella at least partly covering the flow cross section of the media port, which is formed to be elastically bendable by the force of a reaction medium flowing axially through the media port in order to change the useful flow cross section of the media port. A fuel cell stack having a plurality of such single cells is also provided.

Abstract: A fuel cell assembly is provided comprising a membrane electrode assembly that includes a membrane and a first electrode, which is arranged on a first side of the membrane and to which a first gas diffusion layer is assigned. The fuel cell assembly further includes a frame and an adhesive layer directly bonding the membrane electrode assembly to the frame at least in certain areas at an edge area of the membrane electrode assembly. The adhesive layer penetrates the first electrode, and the membrane is directly bonded to the frame as a result of this penetration. A fuel cell system and a fuel cell vehicle comprising such a fuel cell assembly are also provided.

Abstract: A fuel cell assembly has a first gas diffusion layer on the cathode side, a second gas diffusion layer on the anode side, a membrane located between the first gas diffusion layer and the second gas diffusion layer, a first electrode located between the membrane and the first gas diffusion layer and a second electrode located between the membrane and the second gas diffusion layer, and a frame with a recess, held by means of an adhesive layer against the gas diffusion layers. One of the electrodes is arranged on one of the gas diffusion layers to form a gas diffusion electrode, while the other of the electrodes is arranged on the side of the membrane opposite the gas diffusion electrode to form a one-sided membrane electrode arrangement. The electrode-free side of the membrane is bound to the frame directly by the adhesive layer. A fuel cell device and a motor vehicle having a fuel cell device are also provided.
