Membrane-electrode structure (MES) (1) has a membrane (4) between gas diffusion layers. The edge area of the MES is impregnated with a sealing material. A structure that consists of the MES and bipolar plates (6) is compacted. A center area (7) of bipolar plates is set off against its edge area (8) so that the center area is more firmly compressed than the impregnated edge area (3). Independent claims are also included for: (a) A bipolar plate for a fuel cell; (b) and for a fuel cell with a membrane-electrode structure fitted between two bipolar plates; (c) and for a membrane-electrode structure with gas diffusion layers and a membrane between the gas diffusion layers. |
