Claims

1. A media supply plate for a fuel cell stack comprising at least one anode gas terminal and at least one cathode gas terminal, and having at least one anode waste gas terminal and at least one cathode waste gas terminal.

2. The media supply plate of claim 1, wherein at least some of the terminals are connected to gas passages each of which opens into at least one orifice provided on an upper side of the media supply plate.

3. The media supply plate of claim 2, further comprising at least one groove provided adjacent to at least one orifice.

4. The media supply plate of claim 2, further comprising an upper plate provided with the orifices and a lower plate (46) at least contributing to the formation of the gas passages.

5. The media supply plate of claim 1, further comprising at least one aperture provided for the passage of at least one fuel cell stack clamping element.

6. A fuel cell system comprising a media supply plate and a fuel cell stack directly stacked onto the media supply plate.

7. The fuel cell system of claim 6, wherein the fuel cell stack comprises a plurality of identically designed repetitive units.

8. The fuel cell system of claim 6, wherein the fuel cell stack comprises at least two gas passages extending in the stacking direction of the fuel cell stack, each of said gas passages being connected to at least one orifice.

9. The fuel cell system of claim 6, wherein the fuel cell stack is stacked onto the media supply plate so that at least two orifices are located adjacent to the fuel cell stack.

10. The fuel cell system of claim 9, wherein the fuel cell stack is disposed under a first cap, the two orifices disposed adjacent to the fuel cell stack opening into the space under the first cap.

11. The fuel cell system of claim 10, wherein the space under the first cap is divided into a first space and a second space by the fuel cell stack, the one orifice among the orifices located adjacent to the fuel cell stack opening into the first space while the other orifice (28) among the orifices located adjacent to the fuel cell stack opens into the second space.

12. The fuel cell system of claim 11, wherein the fuel cell stack comprises a cathode gas interface opening into the first space and a cathode waste gas interface opening into the second space.

13. The fuel cell system of claim 6, further comprising a fuel cell stack clamping device which retains at least the fuel cell stack and the media supply plate in the stacking direction.

14. The fuel cell system of claim 13, wherein the fuel cell stack clamping device comprises a strip-like fuel cell stack clamping element embracing at least den fuel cell stack.

15. The fuel cell system of claim 14, wherein the strip-like fuel cell stack clamping element is held under tension with the aid of at least one elastic element.

16. The fuel cell system of claim 6, wherein the fuel cell stack is disposed under a second cap.

17. The fuel cell system of claim 6, wherein the fuel cell stack is surrounded by an insulating material.

18. A method for the production of a fuel cell system, in particular a fuel cell system of claim 6 wherein said method comprises the following steps:stacking a fuel cell stack onto a media supply plate, in particular a media supply plate of claim 1;retaining the fuel cell stack with a fuel cell stack clamping device designed to retain the fuel cell stack and the media supply plate in the stacking direction of the fuel cell stack; andheating the fuel cell stack while at the same time retaining it to join the fuel cell stack.

19. The method of claim 18, wherein the heating step comprises supplying and discharging at least one hot gas via at least two terminals.

20. The method of claim 18, wherein a final retaining of the fuel cell stack is effected in its still hot state after joining and with the aid of the fuel cell stack clamping device.
