Description
Stand der TechnikState of the art
Turbokompressoren für ein Brennstoffzellensystem sind aus dem Stand der Technik bekannt, beispielsweise aus der Offenlegungsschrift
Offenbarung der ErfindungDisclosure of the invention
Der erfindungsgemäße Turbokompressor weist demgegenüber eine höhere Effizienz auf, insbesondere wenn er in einem Brennstoffzellensystem verwendet wird. Weiterhin kann er eine Verringerung der Lagerbelastung und eine Verbesserung des Temperaturhaushalts erzielen.In contrast, the turbocompressor according to the invention has a higher efficiency, in particular if it is used in a fuel cell system. Furthermore, it can achieve a reduction of the bearing load and an improvement of the temperature balance.
Dazu umfasst der Turbokompressor eine von einer Antriebsvorrichtung antreibbare Welle. Auf der Welle sind ein Verdichter und eine Abgasturbine angeordnet. Weiterhin ist auf der Welle ein weiterer Verdichter angeordnet. Der Verdichter und der weitere Verdichter bilden einen gemeinsamen Strömungspfad aus, so dass ein Arbeitsfluid stärker verdichtet werden kann als mit nur einem Verdichter. Beispielsweise ist das Arbeitsfluid dabei ein Oxidationsmittel eines Brennstoffzellensystems. Durch diese Anordnung können weitere zwischen dem Verdichter und dem weiteren Verdichter angeordnete Bauteile, beispielsweise Lager, wirkungsvoll mit dem Arbeitsfluid gekühlt werden.For this purpose, the turbocompressor comprises a shaft which can be driven by a drive device. On the shaft, a compressor and an exhaust gas turbine are arranged. Furthermore, a further compressor is arranged on the shaft. The compressor and the further compressor form a common flow path, so that a working fluid can be compressed more than with just one compressor. For example, the working fluid is an oxidizing agent of a fuel cell system. By this arrangement further components arranged between the compressor and the further compressor, for example bearings, can be effectively cooled with the working fluid.
Vorzugsweise sind der Verdichter, der weitere Verdichter und die Abgasturbine jeweils Läuferräder, beispielsweise Radialläufer. Die Abgasturbine ist in einem weiteren Strömungspfad angeordnet bzw. im gleichen Strömungspfad stromabwärts einer Brennstoffzelle, so dass sie das reagierte Oxidationsmittel, also quasi das Abgas der Brennstoffzelle, als Energiequelle nutzt. Durch die Abgasturbine wird somit die Antriebsvorrichtung entlastet.Preferably, the compressor, the further compressor and the exhaust gas turbine are each rotor wheels, for example radial rotor. The exhaust gas turbine is arranged in a further flow path or in the same flow path downstream of a fuel cell, so that it uses the reacted oxidant, so to speak, the exhaust gas of the fuel cell as an energy source. By the exhaust gas turbine thus the drive device is relieved.
In vorteilhaften Ausführungen sind der Verdichter und der weitere Verdichter in einer Luftzuführungsleitung eines Brennstoffzellensystems angeordnet, und die Abgasturbine in einer Abgasleitung des Brennstoffzellensystems. Die Luftzuführungsleitung dient dabei der Zuströmung des Oxidationsmittels in eine Brennstoffzelle, und die Abgasleitung dient der Abfuhr des Oxidationsmittels bzw. des reagierten Oxidationsmittels bzw. einem Gemisch daraus aus der Brennstoffzelle.In advantageous embodiments, the compressor and the further compressor are arranged in an air supply line of a fuel cell system, and the exhaust gas turbine in an exhaust pipe of the fuel cell system. The air supply line serves for the inflow of the oxidizing agent into a fuel cell, and the exhaust gas line serves to remove the oxidizing agent or the reacted oxidizing agent or a mixture thereof from the fuel cell.
In vorteilhaften Weiterbildungen weist die Antriebsvorrichtung einen Stator und einen Rotor auf, ist vorzugsweise also als Elektromotor ausgeführt. Der Rotor ist auf der Welle zwischen dem Verdichter und dem weiteren Verdichter angeordnet. Dadurch kann der Rotor wirkungsvoll mit dem durch die beiden Verdichter geförderten Arbeitsfluid gekühlt werden.In advantageous developments, the drive device has a stator and a rotor, so it is preferably designed as an electric motor. The rotor is arranged on the shaft between the compressor and the further compressor. Thereby, the rotor can be effectively cooled with the working fluid delivered by the two compressors.
Vorteilhafterweise ist die Welle dabei zu beiden Seiten des Rotors mittels je eines Lagers rotierbar gelagert. Die Lager können dazu sowohl als Wälzlager als auch als Gleitlager ausgeführt sein. Vorzugsweise sind der Verdichter auf der einen Seite des Rotors und der weitere Verdichter und die Abgasturbine auf der anderen Seite des Rotors angeordnet. Dadurch ist die Lagerbelastung für beide Lager etwa gleich groß, es können sogar baugleiche Lager verwendet werden.Advantageously, the shaft is rotatably mounted on both sides of the rotor by means of a respective bearing. The bearings can be designed both as a rolling bearing and as a sliding bearing. Preferably, the compressor on one side of the rotor and the further compressor and the exhaust gas turbine are arranged on the other side of the rotor. As a result, the bearing load for both bearings is about the same size, it can even be used identical bearings.
In vorteilhaften Ausführungen sind der Verdichter und der weitere Verdichter axial anströmbar und radial abströmbar ausgeführt. Die beiden Verdichter sind somit als Radialläufer ausgeführt. Die beiden Verdichter können daher als Kreiselpumpen betrachtet werden. Dadurch können vergleichsweise hohe Förderdrücke erzielt werden. Für eine Anwendung in einem Brennstoffzellensystem kann das Oxidationsmittel der Brennstoffzelle so mit einem Druck von mehreren bar zugeführt werden.In advantageous embodiments of the compressor and the further compressor are axially flowed and designed to be radially outflow. The two compressors are thus designed as radial runners. The two compressors can therefore be considered as centrifugal pumps. As a result, comparatively high delivery pressures can be achieved. For an application in a fuel cell system, the oxidant of the fuel cell can be supplied with a pressure of several bar.
In vorteilhaften Weiterbildungen sind der Verdichter und der weitere Verdichter axial aus entgegen gerichteten Richtungen anströmbar. Dadurch können die fluidisch wirksamen Kräfte auf die beiden Verdichter bzw. auf deren Laufräder in axialer Richtung ausgeglichen werden. Vorzugsweise ist es so, dass dazu auch noch das Laufrad der Abgasturbine berücksichtigt wird und die resultierende Axialkraft auf die Welle nahezu Null ist, so dass die Anforderungen an ein Axiallager sehr gering sind bzw. sogar von Radiallagern übernommen werden können. Die Abgasturbine ist dazu vorzugsweise ebenfalls als Radialläufer ausgeführt.In advantageous developments of the compressor and the further compressor can be flowed axially from opposite directions. As a result, the fluidically effective forces on the two compressors or on the wheels in the axial direction can be compensated. Preferably, it is also the case that the impeller of the exhaust gas turbine is taken into account and the resulting axial force on the shaft is almost zero, so that the requirements for a thrust bearing are very low or even can be taken over by radial bearings. The exhaust gas turbine is preferably also designed as a radial runner.
Die beschriebenen Ausführungen des Turbokompressors sind vorzugsweise in einem Brennstoffzellensystem eingesetzt. Das Brennstoffzellensystem weist eine Brennstoffzelle, eine Luftzuführungsleitung zum Zuführen eines Oxidationsmittels in die Brennstoffzelle und eine Abgasleitung zum Abführen des Oxidationsmittels aus der Brennstoffzelle auf. Das abgeführte Oxidationsmittel kann dabei in der Brennstoffzelle vollständig oder teilweise chemisch reagiert haben. Der Verdichter und der weitere Verdichter des Turbokompressors sind in der Luftzuführungsleitung angeordnet. Und die Abgasturbine des Turbokompressors ist in der Abgasleitung angeordnet. Die beiden Druckstufen durch die beiden Verdichter sind in der Luftzuführungsleitung besonders wirksam; zusätzlich kann ein Rotor bzw. Elektromotor des Turbokompressors über die Zuführungsleitung gekühlt werden. Weiterhin können so auch noch die Lager der Welle gekühlt werden. Das aus der Brennstoffzelle ausströmende reagierte Oxidationsmittel kann sehr wirkungsvoll als Leistungsquelle für die Abgasturbine verwendet werden.The described embodiments of the turbocompressor are preferably used in a fuel cell system. The fuel cell system includes a fuel cell, an air supply passage for supplying an oxidant into the fuel cell, and an exhaust passage for discharging the oxidant from the fuel cell. The discharged oxidant may have reacted completely or partially chemically in the fuel cell. The compressor and the further compressor of the turbocompressor are arranged in the air supply line. And the exhaust gas turbine of the turbocompressor is arranged in the exhaust pipe. The two pressure stages through the two compressors are particularly effective in the air supply line; In addition, a rotor or electric motor of the turbocompressor can be cooled via the supply line. Furthermore, even the bearings of the shaft can be cooled. The end the fuel cell effluent reacted oxidant can be used very effectively as a power source for the exhaust gas turbine.
Das Brennstoffzellensystem kann vorzugsweise dazu eingerichtet sein, eine Antriebsvorrichtung eines Kraftfahrzeugs anzutreiben.The fuel cell system may preferably be configured to drive a drive device of a motor vehicle.
