ABSTRACT:
The invention provides a fuel cell arrangement with a plurality of fuel cell stacks which are stacked on top of one another and are enclosed in a sealed exterior housing. Supply air is freely guided to the fuel cell stacks within the enclosure, while combustion gas is provided to the respective stacks by means of pipes. A plurality of flat seals are provided between adjacent fuel cell stacks, each having a central air opening and a separate peripheral combustion gas channel. The lowermost fuel stack is mounted by means of such a seal, on a base plate into which a collective channel for exhaust air and a channel for combustion gas are integrated.
