Abstract: 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).

Abstract: A fuel cell system (100), which includes multiple fuel cell stacks (10, 20) having a pair of adjacent fuel cell stacks (10, 20), namely a first fuel cell stack (10) and a second fuel cell stack (20), each including multiple fuel cells (2), as well as multiple main channels (11, 12, 13) which penetrate the fuel cell stacks (10, 20) for distributing the operating agents to the individual fuel cells (2) is provided. It is provided that the fuel cell stacks (10, 20) of one pair are situated in such a way that a sequence of the main channels (11, 12, 13) is mirror-symmetrical to a plane running between the adjacent fuel cell stacks (10, 20) of the pair, with respect to the different operating agents.
