Definitions
- the invention relates to a Reforra istssystem for generating a hydrogen-rich reformate with a reformer, the fuel and oxidizing agent can be fed.
- the invention further relates to a method for producing a hydrogen-rich reformate with a reformer, the fuel and oxidant can be fed.
- the invention relates to a fuel cell system.
- Reforming systems are used to produce a hydrogen-rich reformate from fuel and oxidants. In fuel cell systems, this reformate can then be fed to a fuel cell assembly which generates electrical energy from the hydrogen and oxygen feedstocks.
- thermodynamic and reaction kinetic processes within the reformer are complex. In particular, they depend on the properties of the substances supplied, that is to say the fuel present as gas or liquid and the air generally supplied as oxidizing agent. In any case, efforts are made to make the processes in the reformer as reproducible as possible, thereby ensuring stable operation of the reforming system and of a fuel cell system.
- the invention has for its object to make the properties of the reformer supplied materials so that a stable reforming operation can take place, and this is to be achieved in particular by efficient and reliable measures with little equipment.
- the invention is based on the generic reforming system in that the fuel supplied to the reformer can be cooled, at least in part, by a fluid which, in addition to the fuel cooling function, also has other components in the reforming system or in a higher-level system in which the reforming system is integrated Has functions. It has been found that the cooling of the fuel supplied to the reformer may have beneficial effects on the operation of the reformer. This applies on the one hand to the temperature of the fuel per se and, on the other hand, to the provision of fuel with a largely unchanged temperature during operation. Such cooling can be provided in a particularly efficient manner by virtue of the fuel entering into a heat exchanging relationship with a fluid which, in addition to the mere cooling function, can also have other functions in the reforming system or in a higher-order system.
- the fluid is air, which is supplied to the reformer as the oxidant. It is also possible that the fluid is air which is used as a cathode feed for a fuel cell arrangement arranged downstream of the reformer.
- Another useful embodiment of the invention is that the fluid is air used as combustion air for an afterburner downstream of the reformer.
- the fluid is cooling fluid, which also serves to cool an internal combustion engine of a motor vehicle, which is equipped with the reforming system.
- the fluid is air, which is used for cooling components of the reformer.
- the reforming system according to the invention can be designed to be particularly useful in that the fluid and the fuel are passed through two nested tubes.
- the process air supplied to the reformer may be introduced through a pipe into the reformer surrounding a fuel pipe.
- Comparable solutions can be chosen in conjunction with other air and liquid flows.
- the invention is based on the generic method in that the fuel supplied to the reformer is at least partially cooled by a fluid which, in addition to the fuel cooling function, also has other functions in the reforming system or in a higher-level system in which the reforming system is incorporated , On the- se way the benefits and specifics of the reforming system of the invention are also implemented in the context of a process. This also applies to the particularly preferred embodiments of the inventive method specified below.
- the fluid is air, which is supplied to the reformer as the oxidant.
- the fluid is air, which is used for a downstream of the reformer Brennstoffzellenan- order as Kathodenzu Kunststoff.
- the fluid is air, which is used for a downstream of the reformer afterburner as combustion air.
- the fluid is cooling fluid, which is also used to cool an internal combustion engine
- the fluid is air, which is used for cooling components of the reformer.
- the method according to the invention can be implemented in a particularly useful way by passing the fluid and the fuel through two nested tubes.
- the invention further relates to a fuel cell system with a reforming system according to the invention.

- This first region 34 exothermic oxidation reactions take place whose products a second area 40 are supplied.
- This second region 40 is supplied by another pump 42 further fuel 46.
- the equipped with a catalyst second area 40 then takes place the actual endothermic reforming, in which a hydrogen-rich reformate 44 is prepared. This can be made available to other applications, in particular a fuel cell stack.
- the pump 36 is adjoined by a fuel line 24, which transports the fuel into the reformer 10.
- blower 38 is followed by a line 28 which transports air 14 into the reformer 10.
- lines 24, 28 are now at least partially arranged so that the air-conveying line 28 surrounds the fuel-carrying line 24, whereby the fuel 12 is cooled.
- FIG. 2 shows a schematic representation of a second embodiment of a reforming system according to the invention.
- the system illustrated here differs from the reforming system described in connection with FIG. 1 with respect to the supply of air and fuel to the first region 34 of the reformer 10.
- the process air 14 used in the first region 34 of the reformer 10 is fed directly to this region 34, without it being used beforehand for cooling fuel.
- the fuel 12 is cooled in this second embodiment by air 16 which, after having performed its cooling function, is supplied to cathodes 18 of a fuel cell stack or afterburner 20.

- a further blower 48 is provided, which transports air via a line 32 to the reforming region 40.
- the conduit 30 for transporting the fuel 46 into the reforming region 40 is at least partially surrounded by the air duct 32.
- the air 22 supplied for this purpose also takes over the cooling of an evaporation region 24, upstream of which the actual reforming region 40 is located.
- FIG. 3 shows an embodiment of a reforming system to which fuel 12 and air 14 are supplied as reactants in a first region 34, while only further fuel 46 is supplied from the outside to a second region 40. It is also conceivable that the two th area 40 additional air is supplied. This process air can also serve to cool the fuel feed.
- the embodiment according to FIG. 3 builds on the embodiment according to FIG. It is also possible to carry out the fuel cooling for the first region 34 of the reformer 10 as described in connection with FIG. 2 and, based thereon, to design a fuel cooling for the second region 40 in the manner shown in FIG 3 is shown. It is also possible to dispense with the fuel cooling for the first region 34.
- FIG. 4 shows a flowchart for explaining a method according to the invention.
- a first step SO1 of the working method according to the invention it is provided that fuel supplied to a reformer is cooled by air.
