Gas chambers (7, 9) in fuel cells (1) are sealed from the environment in a gas-tight manner by means of seals (11). Said seals (11) are exposed to the chemically very aggressive operating gases at high temperature. According to the invention, a fuel cell (1), has a seal (11), arranged between two components (3, 5), made from a carbon-filled, bisphenol cross-linked fluororubber. Said seal (11) is chemically and mechanically extremely stable, such that each fuel cell (1), in a fuel cell block can be sealed and maintained in position within the fuel cell block by means of single seal (11) in a simple manner.
