Description

System aus Brennstoffzelle und WärmetauscherSystem of fuel cell and heat exchanger
Die Erfindung betrifft ein System umfassend eine Brennstoffzelle und einen Wärme- tauscher gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a system comprising a fuel cell and a heat exchanger according to the preamble of claim 1.
Insbesondere bei Hochtemperatur-Brennstoffzellen müssen die in die Brennstoffzelle einzubringenden Reaktanden - beispielsweise die Reaktionsluft - vorerwärmt werden um sie auf ihre Reaktionstemperatur zu bringen. Diese Vorwärmung erfolgt herkömmlicherweise in einem separaten Wärmetauscher, in dem je nach Ausführungsbeispiel auch ein Brenner integriert sein kann. Ein solch separates Bauteil sowie die Strömungsverbindungen zwischen dem Wärmetauscher und der Brennstoffzelle kann eine der Brennstoffzelle vergleichbare Komplexität erreichen, verbraucht Bauraum und verursacht zusätzliches Gewicht.In the case of high-temperature fuel cells in particular, the reactants to be introduced into the fuel cell - for example the reaction air - have to be preheated in order to bring them to their reaction temperature. This preheating is conventionally carried out in a separate heat exchanger in which, depending on the exemplary embodiment, a burner can also be integrated. Such a separate component and the flow connections between the heat exchanger and the fuel cell can achieve a level of complexity comparable to that of the fuel cell, consumes installation space and causes additional weight.
Aufgabe der vorliegenden Erfindung ist es, ein eingangs genanntes System aus Brennstoffzelle und Wärmetauscher derart zu verbessern, dass das Gesamtsystem vereinfacht werden kann, wodurch auch eine Kostensenkung möglich ist. Insbesondere soll eine Reduzierung des Bauraums und des Gewichts sowie eine Funktions- Verbesserung herbeigeführt werden.The object of the present invention is to improve a system of fuel cell and heat exchanger mentioned at the outset in such a way that the overall system can be simplified, which also makes it possible to reduce costs. In particular, a reduction in the installation space and the weight as well as a functional improvement are to be brought about.
Diese Aufgabe wird durch die im Anspruch 1 genannten Merkmale gelöst. Demgemäß ist ein erfindungswesentlicher Gedanke, den Wärmetauscher und die Brennstoffzelle miteinander zu kombinieren, und zwar so, dass der Wärmetauscher unmittelbar an der Brennstoffzelle angeordnet und mit dieser integriert ist. Damit kann ein unmittelbarer Strömungsübergang vom Wärmetauscher zur Brennstoffzelle erreicht werden. Die Luftversorgung über die gesamte Stackoberfläche kann direkt gewährleistet sein. Diese Kopplung spart nicht nur Bauraum sondern auch Gewicht, da auf zusätzliche Gehäuse, Leitungssysteme und andere konstruktive Einrichtungen, wie z. B. ein sog. Manifold verzichtet werden kann. Gemäß einer vorzugsweisen Ausführungsform kann der Wärmetauscher als einfacher Plattenwärmetauscher ausgeführt sein. Je nach Gestaltung des Wärmetauschers kann eine strömungsmäßige Verbesserung der Luftversorgung gegenüber einer Lösung mit Manifold erreicht werden. Zur Erhöhung der Luftvorwärmung ist es überdies möglich, den Wärmetauscher zusätzlich mit einem Brenner auszustatten, so dass das aus der Brennstoffzelle herausgeführte Restgas nachverbrannt wird. Durch die erfolgreiche Verbrennung im Wärmetauscher/Brenner wird diese Restenergie dann ebenfalls - zumindest zum Teil - dem zu erwärmenden Reaktanden zugeführt. Vorzugsweise wird dabei Luft oder Sauerstoff erwärmt.This object is achieved by the features mentioned in claim 1. Accordingly, an idea essential to the invention is to combine the heat exchanger and the fuel cell with one another in such a way that the heat exchanger is arranged directly on the fuel cell and is integrated with it. This enables an immediate flow transition from the heat exchanger to the fuel cell to be achieved. The air supply over the entire stack surface can be guaranteed directly. This coupling not only saves installation space but also weight, since additional housings, line systems and other design devices, such as. B. a so-called manifold can be dispensed with. According to a preferred embodiment, the heat exchanger can be designed as a simple plate heat exchanger. Depending on the design of the heat exchanger, the flow of the air supply can be improved compared to a solution with a manifold. In order to increase the air preheating, it is also possible to additionally equip the heat exchanger with a burner, so that the residual gas led out of the fuel cell is combusted. Due to the successful combustion in the heat exchanger / burner, this residual energy is then also - at least in part - supplied to the reactants to be heated. Air or oxygen is preferably heated.
Eine einfache Ausführungsform der vorliegenden Erfindung wird nachfolgend, auch anhand der beiliegenden Zeichnungen näher erläutert. Die Zeichnungen zeigen inA simple embodiment of the present invention is explained in more detail below, also with reference to the accompanying drawings. The drawings show in

Brennstoffzelle und Wärmetauscher undFuel cell and heat exchanger and
Fig. 2 einen schematischen Aufbau eines herkömmlichen Systems aus Brennstoffzelle und Wärmetauscher.Fig. 2 shows a schematic structure of a conventional system of fuel cell and heat exchanger.
Ein Aufbau, wie er in Fig. 2 dargestellt ist, ist aus dem Stand der Technik bekannt. Dabei wird eine Brennstoffzelle 10, die einen Stack mit einer Vielzahl von parallel zueinander angeordneten Einzelzellen 12 aufweist, mit gasförmigen Reaktanden versorgt, und zwar vorliegend mit einem Brenngas, angedeutet durch den Pfeil 24, und Luft, angedeutet durch den Pfeil 22. Die Luft muss, insbesondere bei einer Hochtemperatur-Brennstoffzelle (z.B. SOFC- Brennstoffzelle), auf ihre Reaktionstemperatur gebracht, also vorerwärmt, werden. Dazu ist ein Wärmetauscher 14 vorgeschaltet, dem über ein Gebläse 18 (nur schematisch dargestellt) in einem Ansaugkanal 16 Luft (vgl. Pfeil 20) zur Verfügung ge- stellt wird und beim Durchfließen des Wärmetauschers 14 auf ihre Betriebstemperatur erwärmt wird.A structure as shown in Fig. 2 is known from the prior art. A fuel cell 10, which has a stack with a plurality of individual cells 12 arranged parallel to one another, is supplied with gaseous reactants, in the present case with a fuel gas, indicated by arrow 24, and air, indicated by arrow 22. The air must be brought to its reaction temperature, ie preheated, especially in the case of a high-temperature fuel cell (eg SOFC fuel cell). For this purpose, a heat exchanger 14 is connected upstream, to which air (see arrow 20) is provided via a fan 18 (only shown schematically) and is heated to its operating temperature when the heat exchanger 14 flows through.
Der Wärmetauscher 14 erhält die zur Erwärmung der Luft notwendige Wärme aus den Abgasen der Brennstoffzelle 10, welche mit Pfeil 24 gekennzeichnet, stromab- wärts der Einzelzellen 12 ebenfalls durch den Wärmetauscher 14 geleitet und anschließend an die Umgebungsluft (Bezugszeichen 28) abgegeben werden. Zudem wird dem Wärmetauscher auch das restliche Brenngas (Bezugszeichen 26) zugeführt. Der Wärmetauscher 14 ist vorliegend gleichzeitig als Brenner ausgebildet, so dass die nicht verbrauchten Reaktanden (Luft, Brenngas) im Wärmetau- scher/Brenner 14 nachverbrannt werden können. Diese zusätzliche Energie dient ebenfalls zur Erwärmung der vorzuwärmenden Luft.The heat exchanger 14 receives the heat necessary for heating the air from the exhaust gases of the fuel cell 10, which is indicated by arrow 24, is also conducted downstream of the individual cells 12 through the heat exchanger 14 and is then released to the ambient air (reference numeral 28). In addition, the remaining fuel gas (reference numeral 26) is also supplied to the heat exchanger. In the present case, the heat exchanger 14 is at the same time designed as a burner, so that the reactants (air, fuel gas) which are not consumed can be re-burned in the heat exchanger / burner 14. This additional energy also serves to heat the air to be preheated.
Durch die herkömmliche Konstruktion mit separatem Wärmetauscher und separater Brennstoffzelle sowie zusätzlichen Leitungen, vorliegend symbolisiert durch die Pfei- le 22, 24 und 26, wird das System relativ komplex, schwer und teuer. Überdies sind sowohl am Brennstoffzelleneingang als auch am Brennstoffzellenausgang Luftverteilungssysteme (sog. Manifolds) notwendig.The conventional design with a separate heat exchanger and separate fuel cell and additional lines, symbolized here by the arrows 22, 24 and 26, makes the system relatively complex, heavy and expensive. In addition, air distribution systems (so-called manifolds) are necessary both at the fuel cell inlet and at the fuel cell outlet.
Die vorliegende Erfindung zielt darauf ab, die Brennstoffzelle und den Wärmetau- scher zu integrieren. Dies ist in Fig. 1 dargestellt. Die Brennstoffzelle 110 besitzt wiederum eine Vielzahl von parallel zueinander angeordneten Einzelzellen 112, die einerseits von dem Brenngas (Bezugszeichen 124) und andererseits von Luft (Bezugszeichen 120) durchströmt werden, wobei durch eine Reaktion dieser beiden Reaktanden ein Stromfluss in der Brennstoffzelle 110 in bekannter Weise generiert wird. In erfindungsgemäßer Weise ist ein Wärmetauscher 114 nun unmittelbar vor dem Stack mit den Einzelzellen 112 derart angeordnet, dass die über einen Ansaugkanal 116 mittels eines Gebläses 118 angesaugte Luft 120 gleichmäßig durch den Wärmetauscher 114 geführt und über den Stack verteilt in die Brennstoffzelle 110 eingebracht wird. Damit bedarf es weder einer zusätzlichen Leitung zwischen dem Wärmetauscher 114 und der Brennstoffzelle 110 noch eines der Brennstoffzelle 110 vorgeschalteten Manifolds.The present invention aims to integrate the fuel cell and the heat exchanger. This is shown in Fig. 1. The fuel cell 110 in turn has a multiplicity of individual cells 112 arranged parallel to one another, through which the fuel gas (reference number 124) and air (reference number 120) flow on the one hand, with a current flow in the fuel cell 110 in a known manner through a reaction of these two reactants is generated. In a manner according to the invention, a heat exchanger 114 is now arranged directly in front of the stack with the individual cells 112 in such a way that the air 120 sucked in via an intake duct 116 by means of a blower 118 is guided uniformly through the heat exchanger 114 and introduced into the fuel cell 110 via the stack. This means that there is no need for an additional line between the heat exchanger 114 and the fuel cell 110 one of the manifolds upstream of the fuel cell 110.
Die aus der Brennstoffzelle 110 über einen Trichter 113 abgeführte Restluft 124 wird möglichst ohne Umwege zum Wärmetauscher 114 zurückgeleitet. Zudem werden die noch nicht verbrannten Brenngase 126 ebenfalls an den Wärmetauscher zurückgeleitet. Der Wärmetauscher 114 besitzt - wie auch im Ausführungsbeispiel gemäß Fig. 2 - einen integrierten Brenner, mit dem die noch nicht verbrauchten Reaktanden aus Luft und Brenngas nachverbrannt werden. Die Abgase aus dem Wärmetauscher/Brenner 114 werden an die Umgebung (Pfeil 128) abgegeben.The residual air 124 discharged from the fuel cell 110 via a funnel 113 is returned to the heat exchanger 114 as far as possible without detours. In addition, the combustion gases 126 which have not yet been burned are likewise returned to the heat exchanger. As in the exemplary embodiment according to FIG. 2, the heat exchanger 114 has an integrated burner with which the reactants from air and fuel gas which have not yet been consumed are afterburned. The exhaust gases from the heat exchanger / burner 114 are released to the environment (arrow 128).
Mit der vorliegenden Erfindung ist es möglich, den Bauraum und das Gewicht gegenüber der herkömmlichen Konfiguration zu reduzieren. Überdies ist eine Verbesserung der Luftversorgung der Stacks von Einzelzellen gegenüber einer Lösung mit einem Manifold möglich. Überdies lässt sich diese Funktion durch eine höhere Leistungsdichte des Gesamtsystems verbessern. With the present invention, it is possible to reduce the space and weight compared to the conventional configuration. It is also possible to improve the air supply to the stacks of individual cells compared to a solution with a manifold. In addition, this function can be improved by a higher power density of the overall system.
