Fuel cell module

1. A fuel cell module comprising:

a fuel cell component;

a residual gas burner component;

a heat exchanger component; and

a compensator providing a flow-carrying connection between two components of the module, said compensator reversibly compensating expansions and bending deformations between said two components of the module, said compensator comprising a corrugated bellows and a protective plate type member arranged inside said corrugated bellows, said protective plate type member being fixed to said compensation member on an incoming flow side end only.

2. A fuel cell module in accordance with claim 1 , wherein said compensator is arranged between said residual gas burner and said heat exchanger.

3. A fuel cell module in accordance with claim 1 , wherein said compensator is arranged between said heat exchanger and said fuel cell.

4. A fuel cell module in accordance with claim 1 , wherein:

said heat exchanger has a deflecting housing;

said fuel cell has a distributor housing; and

said compensator is arranged between said deflecting housing of said heat exchanger and said distributor housing of said fuel cell.

5. A fuel cell module in accordance with claim 1 , wherein said components connected to one another via said compensator have different coefficients of thermal expansion.

6. A fuel cell module in accordance with claim 1 , wherein one of said components connected to one another via said compensator comprises an austenite part or as a nickel-based alloy part made of INCONEL®, while the other component is designed as a ferrite component or as a nickel-based alloy part made of INCONEL®.

7. A fuel cell module in accordance with claim 1 , further comprising another compensator providing a flow-carrying connection between two components of the module to provide two compensators acting in parallel and/or arranged in parallel to one another.

8. A fuel cell module in accordance with claim 1 , wherein said compensator comprises a corrugated bellows.

9. A fuel cell module in accordance with claim 8 , wherein said corrugated bellows is provided with a single-layer or multilayer wall.

10. A fuel cell module in accordance with claim 5 , wherein said compensator has a coefficient of thermal expansion that is between said different coefficients of thermal expansion of the two components connected to one another via said compensator.

11. A fuel cell module in accordance with claim 1 , wherein:

one of said components is an austenite part;

another one of said components is a ferrite component.
