Abstract

A system includes a stack module box, within which is accommodated a fuel cell stack and which stack module box has at least one fuel cell, the fuel cell being in connection with a plurality of media guides leading to the stack module box and from which media can be delivered to the stack module box or received from the stack module box, wherein at least two of the media guides have electrically conductive regions for discharge of current from the fuel cell stack, and/or the wall of the stack module box is electrically conductive in the regions laying opposite to the media guides, and wherein connection lines are led away from the fuel cell stack to the electrically conductive regions and away therefrom. A fuel cell device and a fuel cell vehicle including such a stack module box are also provided.

Claims (13)

1 . A system, comprising:

a stack module box within which is accommodated a fuel cell stack and which fuel cell stack has at least one fuel cell,

the fuel cell stack being in connection with a plurality of media guides leading to the stack module box and from which media can be delivered to the stack module box or received from the stack module box,

wherein at least two of the media guides have electrically conductive regions configured to conduct current away from the fuel cell stack, and/or a wall of the stack module box is electrically conductive in regions opposing the media guides, and

wherein connection lines are led away from the fuel cell stack to the electrically conductive regions of the at least two media guides and/or the wall of the stack module box and away therefrom.

2 . The system according to claim 1 , wherein each electrically conductive region of the wall is in contact with a corresponding one of the electrically conductive regions of the media guides, which is positioned opposite thereof.

3 . The system according to claim 1 , wherein a clamping device of a clamping system is guided around the media guides, and in that the clamping device comprises at least two electrically conductive sections which are electrically insulated from one another and rest against the electrically conductive regions of the media guides.

4 . The system according to claim 3 , wherein the media guides and/or a distribution structure of the stack module box are configured to elastically deform in response to a force applied by the clamping device.

5 . The system according to claim 3 , wherein the clamping device is guided around four media guides in the circumferential direction of the stack module box.

6 . The system according to claim 3 , wherein the clamping device is guided in a longitudinal direction of two of the media guides around the stack module box.

7 . The system according to claim 6 , wherein a plurality of stack module boxes are provided along a path of the clamping device.

8 . A fuel cell device having a system according to claim 1 .

9 . A fuel cell vehicle comprising a fuel cell device according to claim 8 .
