ABSTRACT:
In order to provide a fuel cell unit, comprising a housing which limits at least one gas chamber and has a gas opening in a first housing wall and a gas opening in a second housing wall located opposite the first housing wall, the housing of which has an adequate deformation stability in relation to the sealing surface pressure required for a flat seal even at high temperatures, it is suggested that the fuel cell unit comprise at least one supporting element which is arranged between the first housing wall and the second housing wall and keeps the two housing walls at a distance from one another.
