A fluid chamber device for a reaction unit of a redox device, includes at least one first wall element and at least one second wall element which at least partially delimit a fluid chamber, and a sealing region which closes off the fluid chamber against a fluid exchange, in particular a gas exchange, in relation to a surrounding space. At least one of the wall elements, in an installed state, has at least one sealing contour in the sealing region, which is intended for providing a sealing effect and by means of which a spacing of the at least two wall elements in the sealing region is reduced in relation to a surrounding area of the sealing region.

The invention claimed is: 1. A fluid chamber device for a reaction unit of a redox device, comprising: at least one first wall element and at least one second wall element, which at least partially delimit a fluid chamber; a sealing region which closes off the fluid chamber from a fluid exchange, in particular a gas exchange, in relation to a surrounding space; and at least one electrode, which together with the at least one first wall element and the at least one second wall element, at least partially delimits the fluid chamber, wherein at least one of the wall elements, in an installed state, has at least one sealing contour in the sealing region, which sealing contour is intended for providing a sealing effect and by means of which, a spacing of the at least two wall elements in the sealing region is reduced in relation to a surrounding area of the sealing region, wherein the at least two wall elements are in direct contact with each other in the region of the sealing contour, wherein the sealing contour is embodied in a one-part-implementation with the at least one first wall element, and wherein the at least one first wall element and the sealing contour are made of a same material. 2. The fluid chamber device according to claim 1 , wherein the at least one first wall element and the at least one second wall element each have a sealing surface in the sealing region, which in an installed state provides a gastight sealing effect. 3. The fluid chamber device according to claim 2 , wherein the sealing surfaces are each of substantially strip-like design. 4. The fluid chamber device according to claim 3 , wherein the sealing surfaces have a width of at most 1 mm. 5. The fluid chamber device according to claim 2 , further comprising: at least one tensioning part element which is designed as a frame which encompasses the fluid chamber device and by screwing action exerts a pressure upon the fluid chamber device, and which provides a pressing force acting upon the sealing surfaces for a pressure-resistant sealing effect. 6. The fluid chamber device according to claim 5 , further comprising: at least one spacer element arranged between the at least one first wall element and the at least one second wall element, which spacer element is provided for limiting the pressing force acting upon the sealing surfaces. 7. The fluid chamber device according to claim 2 , wherein the at least one sealing contour is embodied as a bulge of the at least one wall element, which bulge has a crest on which is arranged the sealing surface of the at least one other wall element. 8. The fluid chamber device according to claim 1 , wherein the wall elements are implemented from at least substantially different materials. 9. The fluid chamber device according to claim 1 , wherein a main extent of the wall elements is at least 30 times a height of the fluid chamber. 10. The fluid chamber device according to claim 1 , wherein at least one of the wall elements has a fluid-permeable partial region. 11. A redox device having at least one first fluid chamber device and at least one second fluid chamber device each according to claim 1 . 12. The redox device according to claim 11 , wherein the fluid chamber devices are arranged directly adjacent to each other in a direction which is perpendicular to a main extent. 13. The redox device according to claim 11 , wherein the fluid chamber devices are arranged in a mirror-image manner in relation to each other in a direction which is perpendicular to a main extent. 14. A fluid chamber device for a reaction unit of a redox device, comprising: at least one first wall element, consisting of an electrical insulating material; at least one second wall element, consisting of an electrical conductive material; at least one electrode, which is formed as a section of the second wall element; and a sealing region, which closes off the fluid chamber from a fluid exchange, in particular a gas exchange, in relation to a surrounding space, wherein the at least one first wall element, the at least one second wall element and the at least one electrode at least partially delimit a fluid chamber, wherein the at least one first wall element has, in an installed state, in the sealing region at least one sealing contour, which is intended for providing a sealing effect, and wherein the at least one first wall element and the at least one second wall element are embodied of a material which is different from a rubber-like elastic material. 15. The fluid chamber device according to claim 14 , wherein the sealing contour is embodied in an one-part-implementation with the at least one first wall element, and wherein the at least one first wall element and the sealing contour are made of a same material. 16. The fluid chamber device according to claim 1 , further comprising at least one spacer element arranged between the at least one first wall element and the at least one second wall element, which spacer element is provided for limiting the pressing force acting upon the sealing surfaces and which has a material elasticity which is lower than a lowest material elasticity of the at least one first wall element and/or the at least one second wall element. 17. The fluid chamber device according to claim 1 , further comprising at least one membrane which is arranged at least partially in the at least one second wall element. 18. The fluid chamber device according to claim 17 , wherein the at least one second wall element comprises at least one receiving region in which the at least one membrane is arranged, and wherein the at least one membrane directly abuts on the at least one second wall element. 19. The fluid chamber device according to claim 1 , wherein the electrode is formed as a section of the at least one second wall element and is partially embodied in an one-port-implementation with the at least one second wall element. 20. A fluid chamber device for a reaction unit of a redox device, comprising: at least one first wall element and at least one second wall element, which at least partially delimit a fluid chamber; a sealing region which closes off the fluid chamber from a fluid exchange, in particular a gas exchange, in relation to a surrounding space; and and at least one electrode, which together with the at least one first wall element and the at least one second wall element at least partially delimits the fluid chamber, wherein at least one of the wall elements, in an installed state, has at least one sealing contour in the sealing region, which sealing contour is intended for providing a sealing effect and by means of which a spacing of the at least two wall elements in the sealing region is reduced in relation to a surrounding area of the sealing region, wherein the at least two wall elements are in direct contact with each other in the region of the sealing contour, further comprising at least one membrane which is arranged at least partially in the at least one second wall element, wherein the at least one second wall element comprises at least one receiving region in which the at least one membrane is arranged, and wherein the at least one membrane directly abuts on the at least one second wall element.
