A device for mixing fluids, in particular a gas injection valve, nozzle valve, mixing nozzle or jet compressor, is proposed. To that end, a first fluid-carrying device (12) for carrying a first fluid and a second fluid-carrying device (13) for carrying a second fluid are provided; the fluids are mixed with one another in a mixing region (16) that is in communication with the fluid-carrying devices (12, 13). In addition, a means (20) for generating turbulence in the applicable fluid and a heater, with which the fluid can be heated before reaching the mixing region (16), disposed downstream of the means (20) for generating turbulence in terms of the flow direction of the applicable fluid are associated with at least one of the fluid-carrying devices (12, 13) . The proposed device is used in particular for mixing hydrogen and saturated steam and to deliver this mixture to a fuel cell.

What is claimed is: 1. A device for mixing steam and hydrogen in fuel cell device in the form of a gas injection valve, mixing nozzle or jet compression nozzle, having a first fluid-carrying device (12) for carrying a first fluid in the form of hydrogen and a second fluid-carrying device (13) for c
What is claimed is: 1. A device for mixing steam and hydrogen in fuel cell device in the form of a gas injection valve, mixing nozzle or jet compression nozzle, having a first fluid-carrying device (12) for carrying a first fluid in the form of hydrogen and a second fluid-carrying device (13) for carrying a second fluid in the form of steam, wherein the steam and hydrogen are mixed with one another in a mixing region ( 16) that is in communication with the fluid-carrying devices ( 12, 13), and wherein a means (20) for generating turbulence in the applicable fluid and a heater, with which the fluid is heatable before reaching the mixing region (16), downstream of the means (20) for generating turbulence in terms of the flow direction of the applicable fluid are associated with at least one of the fluid-carrying devices (12, 13). 2. The device of claim 1, wherein the means (20) for generating turbulence has a body that is exposed to or introduced into the flow of the fluid, wherein the body is selected from the group consisting of a rod (20) or an arrangement of rods, a ring or an arrangement of rings, a small plate, a perforated screen, a shower head, or a sieve. 3. The device of claim 1, wherein the means (20) for generating turbulence is embodied and/or disposed such that the most effective-possible heating of the fluid subsequently exposed to the heater takes place. 4. The device of claim 1, wherein the heater is an electric heater, and it has a heating wire (14, 14') or heating ring, or an arrangement of heating wires (14, 14') or heating rings. 5. The device of claim 1, wherein the first fluid-carrying device (12) is formed at least in some regions by an cylindrically symmetrical recess in a base body (18), which recess discharges into a central conduit (23) made in the base body (18). 6. The device of claim 5, wherein the central conduit ( 20) leads to an outlet (10) from the fluid mixing device ( 5) and widens in funnel-like fashion in an area surrounding of the outlet (10). 7. The device of claim 5, wherein the second fluid-carrying device (13) is inserted symmetrically into the recess in the base body (18) and discharges into the central conduit ( 23) made in the base body (18). 8. The device of claim 1, wherein the first fluid-carrying device (12) and/or the second fluid-carrying device (13) has at least approximately the shape of a funnel, a cartridge, or a nozzle. 9. The device of claim 1, wherein the second fluid-carrying device (13) sprays the second fluid carried in it into the central conduit (23) in the mixing region (16) and thereby mixes it with the first fluid carried in the first fluid-carrying device (12 ). 10. A device for mixing steam and hydrogen in fuel cell device in the form of a gas injection valve, mixing nozzle or jet compression nozzle, having a first fluid-carrying device (12) for carrying a first fluid and a second fluid-carrying device (13) for carrying a second fluid, wherein the fluids are mixed with one another in a mixing region (16) that is in communication with the fluid-carrying devices (12, 13), and wherein a means (20) for generating turbulence in the applicable fluid and a heater, with which the fluid is heatable before reaching the mixing region (16), downstream of the means (20) for generating turbulence in terms of the flow direction of the applicable fluid are associated with at least one of the fluid-carrying devices (12, 13), wherein the heater is disposed directly downstream of the means (20) for generating turbulence, and is spaced apart parallel from it. 11. A device for mixing steam and hydrogen in fuel cell device in the form of a gas injection valve, mixing nozzle or let compression nozzle, having a first fluid-carrying device (12) for carrying a first fluid and a second fluid-carrying device (13) for carrying a second fluid, wherein the fluids are mixed with one another in a mixing region (16) that is in communication with the fluid-carrying devices (12, 13), and wherein a means (20) for generating turbulence in the applicable fluid and a heater, with which the fluid is heatable before reaching the mixing region (16), downstream of the means (20) for generating turbulence in terms of the flow direction of the applicable fluid are associated with at least one of the fluid-carrying devices (12, 13), wherein at least one of the fluid-carrying devices (12, 13) is provided in at least some regions superficially with a coating (25) of Teflon, which counteracts an adhesion, precipitation, or condensation of the applicable fluid or ingredients contained therein. 12. The device of claim 11, wherein the second fluid-carrying device (13), which is inserted into the recess of the base body (18) and is contact on its outside (24) with the first fluid, is provided with the coating (25) on this outside (24 ), at least in some regions and in an area surrounding the mixing region (16).
