Definitions
- the invention relates to a fuel cell system comprising a reformer with a burner unit for reacting fuel with oxidizing agent in an exothermic oxidation reaction to form a product gas, which downstream of the burner unit with additional fuel is miscible, wherein the resulting gas mixture in the reformer is convertible to reformate ; a fuel cell stack, to which the reformate can be supplied; and an afterburner to which substances reacted in the fuel cell stack can be supplied, with a burner unit for reacting fuel with oxidizing agent in an exothermic oxidation reaction.
- the invention relates to a motor vehicle with such a fuel cell system.
- Fuel cell systems are used to convert chemical energy into electrical energy.
- the central element in such systems is a fuel cell in which electrical energy is released by the controlled conversion of hydrogen and oxygen.
- Fuel cell systems must be able to process common fuels in practice. Since hydrogen and oxygen are converted in a fuel cell, the fuel used must be prepared in such a way that the gas supplied to the anode of the fuel cell has the highest possible proportion of hydrogen - this is the task of the reformer.
- a reformer fuel and oxidizing agent preferably air, fed. In the former then takes place a reaction of the fuel with the oxidizing agent, for example by the process of partial oxidation is performed.
- a reformer of the prior art is known from DE 103 59 205 Al.
- an afterburner is provided in the fuel cell system.
- the afterburner performs as complete a combustion as possible in order to leave as few pollutants as possible in the combustion exhaust gas.
- An afterburner of the prior art is known from DE 10 2004 049 903 A1.
- the object of the present invention is to develop generic fuel cell systems and motor vehicles such that cost savings can be achieved.
- the fuel cell system according to the invention builds on the generic state of the art in that the burner unit of the reformer is constructed identical to the burner unit of the afterburner.
- cost savings result in two respects. To the On the one hand, it is more cost-effective to produce a burner unit in only one design and, on the other hand, further cost savings can be realized by a piece-rate effect because it requires twice as many burner units of the remaining type and the unit price decreases with increasing number of units.
- the burner unit of the reformer and the burner unit of the afterburner each having a fuel injector.
- the above-mentioned advantages can be achieved in the context that the burner unit of the reformer and the burner unit of the afterburner each have an evaporation-type fuel supply device. Furthermore, the invention relates to a motor vehicle with such a fuel cell system, with which the above-described advantages can be achieved in a transferred manner.
- FIG. 1 shows a schematic representation of a fuel cell system according to a preferred embodiment.
- FIG. 1 shows a schematic representation of a fuel cell system according to a preferred embodiment.
- the fuel cell system 10 installed in a motor vehicle comprises a reformer 12, which has a first fuel line 14 from a fuel tank 16
- Fuel is supplied. Furthermore, fuel is supplied to the reformer 12 at a further feed point by means of a second fuel train 18 from the fuel tank 16.
- the fuel types are diesel, gasoline, biogas, natural gas and others known from the prior art
- the reformer 12 is supplied with oxidizing agent, for example air, via a first oxidizing agent strand 22.
- the reformer 12 comprises a burner unit 48, which has a primary fuel feed device, by means of which the burner unit 48 can be supplied with fuel.
- the primary fuel supply device is connected to the first fuel train 14.
- the burner unit 48 comprises an oxidant supply device connected to the first oxidant strand 22, by means of which oxidizing agent can be fed to the burner unit 48.
- a reaction of fuel and oxidant takes place in a combustion or exothermic complete oxidation reaction.
- the resulting hot product gas stream then enters the downstream, ie right in Fig. 1 in a mixing zone 50 a.
- additional fuel is added to the resulting product gas by means of a secondary fuel supply device 20.
- each of the primary and secondary fuel supply means is an injection nozzle, and preferably a Venturi nozzle, but the fuel may be supplied to the burner unit 48 and the mixing zone 50, respectively, by means of an evaporative type fuel supply device having a porous evaporation unit.
- the secondary fuel supply device 20 is connected to the second fuel line 18.
- the mixing zone 50 is supplied with oxidizing agent.
- the mixed with the additional fuel gas mixture enters a reforming zone 52, where it is reacted in an endothermic reaction with in a hydrogen-rich gas mixture, preferably by means of a catalyst arranged there.
- This reformate, ie hydrogen-rich gas mixture leaves the reformer 12 via the Reformatstrang 24 and is available for further use for the fuel cell stack 26.
- the reformate is reacted in the fuel cell stack 26 with the aid of cathode feed through a cathode feed line 28 to generate electricity and heat.
- the generated power can be tapped off via electrical connections 30.
- the anode exhaust gas is over an anode exhaust line 32 of a mixing unit 34 of an afterburner 36 supplied.
- the afterburner 36 can be supplied with fuel from the fuel tank 16 via a third fuel line 38. Further, the afterburner 36 via a second oxidant strand 40 oxidizing agent can be fed.
- the afterburner 36 includes a burner unit 54, which has a fuel supply device, via which the burner unit 54 fuel is supplied.
- the fuel supply device is connected to the third fuel line 38.
- the burner unit 54 comprises an oxidizing agent supply device connected to the second oxidant strand 40, by means of which oxidizing agent can be supplied to the burner unit 54.
- reaction of fuel and oxidant takes place in an exothermic oxidation reaction, i. as complete a combustion as possible.
- the resulting combustion exhaust gases then pass downstream, i. right in Fig. 1 in a mixing zone 56 a.
- Mixing zone 56 is added to the resulting exhaust gases by means of a mixing unit 34 anode exhaust gas.
- the mixed with the anode exhaust gas mixture enters a combustion zone 58, which is filled in the embodiment shown by a porous body in which the gas mixture burns almost completely, i. the gas mixture burns up on the pore body in the combustion zone 58.
- the combustion exhaust gas from the afterburner 36 which is mixed in a mixing unit 42 with cathode exhaust air, which is conveyed via a Kathodenabuftstrang 44 from the fuel cell stack 26 to the mixing unit 42, flows through a heat exchanger 46 for preheating the cathode. finally leaves the fuel cell system 10.
- the individual zones of the reformer 12, i. the zone receiving the burner unit 48, the mixing zone 50 and the reforming zone 52, as well as the individual zones of the afterburner 36, i. the zone receiving the burner unit 54, the mixing zone 56 and the combustion zone 58 are separated from one another in FIG. 1 by dashed lines or by solid lines.
- the zones may be separated by structural features or blended into each other.
- corresponding delivery devices such as, for example, pumps or blowers and / or control valves for flow regulation, may be provided in the fuel strands 14, 18 and 38, in the oxidant strands 22 and 40 and in the cathode air strands 28.
