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.
Claims4
A fuel cell module comprising:
- a plurality of fuel cell stacks stacked on top of one another;
- a combustion gas supply connected to said fuel cell stacks by means of pipes;
- a closed housing enclosing the fuel cell stacks and defining an air supply therein, air in said air supply surrounding said fuel cell stacks and being in flow communication therewith;
- and
- a plurality of flat seals (11) provided between each of the fuel cell stacks (1) that are located on top of one another in the stack, said seal having a central air opening (22) and a peripheral, separate combustion gas channel (24);
- wherein the lowermost fuel cell stack (1) is mounted by one of said seals (11) on a base plate (6), into which base plate a collecting channel (5) for the exhaust air and a channel (9) for the combustion gas are integrated.
