| Zusammenfassung: | The invention relates to a fuel cell (10) having a stack comprising a bipolar plate (20) which has a flow field (22) formed by a profiled section of the bipolar plate (20), and an elongated sealing element (21) which at least partially surrounds the flow field (22), and a membrane electrode assembly (30). It is provided that, inside a cavity (25) formed between the membrane electrode assembly (30) and the bipolar plate (20) in a region between the sealing element (21) and the flow field (22), a filling agent (24) is arranged which extends in the extension direction of the cavity (25). |
