Description
Dispositif et procédé d'alimentation en air d'un systèmeDevice and method for supplying air to a system
auxiliaire pile à combustible L'invention concerne les piles à combustible et en particulier un dispositif et un procédé d'alimentation en air d'un système auxiliaire pile à combustible. The invention relates to fuel cells and in particular to a device and method for supplying air to a fuel cell auxiliary system.
Les piles à combustible sont notamment utilisées pour fournir de l'énergie électrique nécessaire à la propulsion de io véhicules automobiles. La pile à combustible est alors embarquée à bord du véhicule. Fuel cells are used in particular to provide electrical energy necessary for the propulsion of motor vehicles. The fuel cell is then embarked on board the vehicle.
Une pile à combustible est constituée principalement de deux électrodes, une anode et une cathode, qui sont séparées par un électrolyte. Ce type de pile permet la conversion directe en énergie électrique de l'énergie produite par les réactions d'oxydo-réduction suivantes: - une réaction d'oxydation d'un combustible, ou carburant, qui alimente l'anode en continu; et - une réaction de réduction d'un comburant qui alimente la 20 cathode en continu. A fuel cell consists mainly of two electrodes, anode and a cathode, which are separated by an electrolyte. This type of cell allows the direct conversion into electrical energy of the energy produced by the following oxidation-reduction reactions: an oxidation reaction of a fuel, or fuel, which feeds the anode continuously; and a reduction reaction of an oxidant which feeds the cathode continuously.
Les piles à combustible utilisées pour fournir de l'énergie électrique à bord de véhicules automobiles sont généralement du type à électrolyte solide, notamment à électrolyte formé par une membrane en polymère. Une telle pile utilise notamment de l'hydrogène (H2) et de l'oxygène (02) en guise de combustible et de comburant respectivement. The fuel cells used to supply electrical energy in motor vehicles are generally of the solid electrolyte type, in particular with an electrolyte formed by a polymer membrane. Such a cell uses in particular hydrogen (H2) and oxygen (02) as fuel and oxidant respectively.
Contrairement aux moteurs thermiques qui rejettent avec les gaz d'échappement une quantité non négligeable de substances polluantes, la pile à combustible offre notamment l'avantage de rejeter principalement de l'eau qui est produite par la réaction de réduction à la cathode. Unlike thermal engines that discharge with the exhaust gas a significant amount of polluting substances, the fuel cell offers the particular advantage of rejecting mainly water that is produced by the reduction reaction at the cathode.
La pile rejette aussi une partie du comburant qui n'a pas réagi sous forme de gaz d'évacuation cathodique et elle rejette éventuellement une partie du carburant qui n'a pas réagi sous forme de gaz d'évacuation anodique. Dans ce dernier cas, le carburant est généralement brûlé avant d'être rejeté dans l'atmosphère sous forme de gaz d'échappement. The cell also rejects a portion of the unreacted oxidant as cathodic evacuation gas and eventually rejects a portion of the unreacted fuel as anode exhaust gas. In the latter case, the fuel is usually burned before being released into the atmosphere as exhaust gas.
L'unité auxiliaire de production d'électricité (APU) est une application de la pile à combustible destinée à générer de la puissance électrique pour les équipements électriques d'un véhicule conventionnel. L'APU peut soit remplacer l'alternateur, soit être exclusivement destiné à de nouveaux équipements électriques (par exemple: climatisation électrique en io remplacement de la climatisation mécanique). The auxiliary power generation unit (APU) is an application of the fuel cell for generating electrical power for the electrical equipment of a conventional vehicle. The APU can either replace the alternator or be exclusively intended for new electrical equipment (for example: electric air conditioning by replacing the mechanical air conditioning).
Dans un véhicule classique utilisant un moteur à combustion interne pour générer la puissance mécanique nécessaire à l'avancement du véhicule, il est intéressant d'ajouter un système pile à combustible de type APU qui génère is une puissance électrique importante (de l'ordre de quelques kW) utile pour répondre aux besoins de puissance électrique toujours croissants dans les véhicules. In a conventional vehicle using an internal combustion engine to generate the mechanical power necessary for the advancement of the vehicle, it is advantageous to add an APU fuel cell system which generates is a significant electrical power (of the order of a few kW) useful for meeting ever increasing electrical power requirements in vehicles.
Le générateur d'électricité pile à combustible de type APU peut soit fonctionner avec un carburant liquide en utilisant un reformeur qui permet de transformer l'essence ou le diesel (ou tout type de carburant identique à celui utilisé par le moteur à combustion interne du véhicule afin d'avoir un réservoir de carburant unique) en hydrogène et assurant ainsi l'alimentation de la pile à combustible, soit fonctionner avec un stockage d'hydrogène embarqué dans le véhicule. La pile à combustible transforme cet hydrogène avec l'oxygène de l'air pour créer une puissance électrique. Pour fonctionner cet APU a besoin d'air sous forme comprimé. II est donc nécessaire d'inclure dans le périmètre de l'APU un système de compression d'air. The APU type fuel cell electricity generator can either operate with a liquid fuel using a reformer that can convert gasoline or diesel (or any type of fuel identical to that used by the vehicle's internal combustion engine in order to have a single fuel tank) hydrogen and thus ensuring fuel cell fuel, either operate with a hydrogen storage embedded in the vehicle. The fuel cell converts this hydrogen with oxygen from the air to create electric power. To work this APU needs air in compressed form. It is therefore necessary to include in the perimeter of the APU an air compression system.
L'APU pile à combustible essence ou diesel permet l'utilisation d'un carburant classique de type liquide qui est celui utilisé par le moteur à combustion interne du véhicule. En phase de fonctionnement normal, le système reformeur reforme le carburant et produit un débit de reformât riche en hydrogène. The APU gasoline or diesel fuel cell allows the use of a conventional liquid type fuel that is the one used by the internal combustion engine of the vehicle. In normal operation, the reformer system reformulates the fuel and produces a hydrogen-rich reformate flow.
L'APU pile à combustible peut également fonctionner avec un stockage d'hydrogène embarqué. L'hydrogène alimente la pile à combustible qui délivre un courant électrique permettant d'assurer la génération électrique. The APU fuel cell can also operate with onboard hydrogen storage. Hydrogen feeds the fuel cell which delivers an electric current to ensure electrical generation.
Plusieurs piles à combustible utilisent un système de compression d'air permettant de générer l'air comprimé pour alimenter le reformeur et le stack. Ces systèmes de compression comprennent au moins un étage de compression afin d'assurer le niveau de pression nécessaire au fonctionnement du système i0 APU. Many fuel cells use an air compression system to generate compressed air to power the reformer and the stack. These compression systems comprise at least one compression stage to provide the pressure level necessary for the operation of the APU system.
Le brevet US-2003/0064260A1 propose de lier le fonctionnement du moteur à combustion interne avec le système pile à combustible. Un problème avec ce système est que pour augmenter la pression, un compresseur supplémentaire est is nécessaire. US-2003 / 0064260A1 proposes to link the operation of the internal combustion engine with the fuel cell system. A problem with this system is that to increase the pressure, an additional compressor is needed.
L'objet de la présente invention est de fournir un dispositif et un procédé d'alimentation en air d'un système auxiliaire pile à combustible APU amélioré. The object of the present invention is to provide a device and method for supplying air to an improved APU fuel cell auxiliary system.
La présente invention propose une installation de production d'électricité à bord d'un véhicule automobile du type décrit précédemment, caractérisée en ce que le véhicule comporte un moteur à combustion interne équipé d'un surcompresseur et en ce que c'est ledit surcompresseur qui alimente ladite pile à combustible en air. The present invention proposes an installation for producing electricity on board a motor vehicle of the type described above, characterized in that the vehicle comprises an internal combustion engine equipped with a supercharger and in that it is said supercharger which feeds said fuel cell with air.
Un avantage de la présente invention est d'utiliser un surcompresseur déjà présent dans le véhicule pour l'alimentation en air du moteur à combustion interne dans le but supplémentaire d'alimenter en air l'APU. An advantage of the present invention is to use a supercharger already present in the vehicle for the air supply of the internal combustion engine for the additional purpose of supplying air to the APU.
Selon d'autres caractéristiques de l'invention: - le compresseur est entraîné par une turbine récupérant l'énergie des gaz d'échappement nécessaire à entraîner ledit compresseur en rotation. According to other characteristics of the invention: the compressor is driven by a turbine recovering the energy of the exhaust gases necessary to drive said compressor in rotation.
- la turbine et le compresseur forment un turbocompresseur. the turbine and the compressor form a turbocharger.
- l'installation comprend un reformeur qui alimente la pile à combustible en carburant et qui rejette des gaz d'échappement issus du moteur qui sont injectés dans la turbine. the installation comprises a reformer which supplies the fuel cell with fuel and which rejects exhaust gases from the engine which are injected into the turbine.
- l'installation comprend un système de vannes permettant de 5 contrôler les débits et les pressions d'air à l'entrée de la pile à combustible et du moteur à combustion interne. the installation comprises a system of valves making it possible to control the flow rates and the air pressures at the inlet of the fuel cell and of the internal combustion engine.
- la pile à combustible est une unité auxiliaire d'électricité (APU). - the fuel cell is an auxiliary electricity unit (APU).
La présente invention fournit en outre un procédé d'alimentation en air d'un système pile à combustible, de io préférence une unité auxiliaire de puissance (APU), le procédé opérant en fournissant un moteur à combustion interne constitué d'un surcompresseur prévu pour alimenter les cylindres dudit moteur; et en alimentant ladite pile à combustible en air comprimé par ledit surcompresseur si le moteur à combustion interne est en fonctionnement et si ladite pile à combustible est en fonctionnement. The present invention further provides a method of supplying air to a fuel cell system, preferably an auxiliary power unit (APU), the method operating by providing an internal combustion engine consisting of a supercharger provided for supplying the cylinders of said engine; and supplying said fuel cell with compressed air by said supercharger if the internal combustion engine is in operation and said fuel cell is in operation.
Le même procédé, opérant, si le moteur à combustion interne ne fonctionne pas et si ladite pile à combustible est en fonctionnement, en alimentant ledit surcompresseur par un 20 moteur électrique. The same method, operating, if the internal combustion engine does not operate and said fuel cell is in operation, supplying said supercharger with an electric motor.
Le procédé comporte aussi un contrôle du débit d'air alimentant la pile à combustible qui est assuré par le contrôle de la vitesse de rotation du moteur du compresseur. The method also includes a control of the air flow supplying the fuel cell which is ensured by the control of the rotational speed of the compressor motor.
L'invention peut s'appliquer à un véhicule comprenant une installation de production d'électricité, du type comprenant une pile à combustible permettant d'alimenter en air ladite pile à combustible par un surcompresseur ou utilisant un procédé d'alimentation en air d'un système pile à combustible. The invention can be applied to a vehicle comprising an electricity generating installation, of the type comprising a fuel cell for supplying air to said fuel cell by a supercharger or using an air supply method of a fuel cell system.
La présente invention sera mieux comprise à l'étude d'un 30 mode de réalisation pris à titre d'exemple nullement limitatif et illustré par les dessins annexés, sur lesquels: - la figure 1 présente le moteur à combustion interne couplé au turbocompresseur; - la figure 2 présente le moteur à combustion interne dont le turbocompresseur sert également à alimenter en air le système APU. The present invention will be better understood from the study of an embodiment taken by way of nonlimiting example and illustrated by the accompanying drawings, in which: - Figure 1 shows the internal combustion engine coupled to the turbocharger; - Figure 2 shows the internal combustion engine whose turbocharger is also used to supply air to the APU system.
En référence aux figures, l'invention comprend: - un moteur à combustion interne, non représenté entièrement, qui comprend en particulier un ensemble turbocompresseur 1 permettant, grâce au compresseur 2, d'alimenter en air les cylindres 3 du moteur et, grâce à la turbine 4, de récupérer l'énergie des gaz d'échappement pour faire io tourner le compresseur 2. With reference to the figures, the invention comprises: an internal combustion engine, not entirely represented, which comprises in particular a turbocharger assembly 1 enabling, thanks to the compressor 2, to supply air to the cylinders 3 of the engine and, thanks to the turbine 4, to recover the energy of the exhaust gases to turn the compressor 2.
- un système pile à combustible APU 5 qui comprend: É un reformeur de carburant, non représenté, permettant de transformer le carburant liquide en un reformât riche en hydrogène pour alimenter la pile 5 côté anode, ou un stockage 15 d'hydrogène embarqué, É une pile à combustible qui transforme l'hydrogène avec l'oxygène de l'air en une puissance électrique, et É un couplage 6 entre le turbocompresseur du moteur à combustion interne et le système APU 5 (les lignes d'alimentation en air de I'APU proviennent du compresseur et deux vannes 7 et 8 permettent de réguler les débits d'alimentation). an APU fuel cell system which comprises: a fuel reformer, not shown, for converting the liquid fuel into a hydrogen-rich reformate for supplying the anode-side battery, or on-board hydrogen storage, a fuel cell that converts hydrogen with oxygen from the air into electrical power, and É a coupling 6 between the turbocharger of the internal combustion engine and the APU system 5 (the air supply lines of I APU come from the compressor and two valves 7 and 8 regulate the flow rates).
La description du fonctionnement de ce couplage 6 entre le moteur et I'APU 5 est faîte pour deux phases de 25 fonctionnement distinctes: - Quand, le moteur à combustion interne est en fonctionnement, la turbine 4 du turbocompresseur 1 est alimentée par les gaz d'échappement du moteur. Le compresseur 2 fonctionne grâce à l'énergie apportée par la turbine 4 et alimente en air le moteur. The description of the operation of this coupling 6 between the motor and the APU 5 is made for two distinct operating phases: When the internal combustion engine is in operation, the turbine 4 of the turbocharger 1 is supplied by the combustion gases. engine exhaust. The compressor 2 operates thanks to the energy provided by the turbine 4 and supplies the engine with air.
Dans cette phase et en cas de fonctionnement de I'APU 5, celui-ci est alimenté par l'air comprimé par le turbocompresseur 1. Le débit est partagé entre les deux alimentations grâce à l'addition d'une vanne 8 contrôlant le débit d'entrée dans I'APU 5. In this phase and in case of operation of the APU 5, it is powered by compressed air by the turbocharger 1. The flow is shared between the two power supplies through the addition of a valve 8 controlling the flow entry into the APU 5.
- Quand le moteur à combustion interne ne fonctionne pas, la turbine 4 du turbocompresseur 1 n'est pas alimentée en énergie: le compresseur 2 ne peut pas fonctionner grâce à la turbine 4. La vanne 7 d'entrée de l'alimentation en air dans le moteur à combustion interne est fermée. When the internal combustion engine does not operate, the turbine 4 of the turbocharger 1 is not supplied with energy: the compressor 2 can not operate thanks to the turbine 4. The inlet valve 7 of the air supply in the internal combustion engine is closed.
Dans ce cas, si l'APU 5 doit fonctionner, le compresseur 2 du turbocompresseur 1 fonctionne grâce à l'alimentation du io moteur électrique 9 du turbocompresseur 1. La vanne 8 en entrée de l'APU 5 est grande ouverte et le contrôle du débit d'air alimente l'APU 5 est assuré par le contrôle de la vitesse de rotation du moteur 9 du compresseur 2. In this case, if the APU 5 is to operate, the compressor 2 of the turbocharger 1 operates by the power supply of the electric motor 9 of the turbocharger 1. The valve 8 at the input of the APU 5 is wide open and the control of the air flow feeds the APU 5 is ensured by the control of the speed of rotation of the motor 9 of the compressor 2.
L'homme du métier appréciera le fait que, si le mode non limitatif de l'invention est décrit avec un turbocompresseur, l'invention ne se limite pas à cette façon de comprimer l'air. Au lieu d'un turbocompresseur, d'autres formes de surcompresseur peuvent être utilisées, par exemple un surcompresseur entraîné par une courroie. Those skilled in the art will appreciate the fact that, if the non-limiting mode of the invention is described with a turbocharger, the invention is not limited to this way of compressing the air. Instead of a turbocharger, other forms of supercharger can be used, for example a belt driven supercharger.
Une telle installation permet d'assurer la compression et l'alimentation de l'air nécessaire au fonctionnement de l'APU 5 grâce au turbocompresseur 1 existant pour l'alimentation en air du moteur à combustion interne du véhicule. Such an installation makes it possible to ensure the compression and supply of the air necessary for the operation of the APU 5 by virtue of the existing turbocharger 1 for supplying air to the internal combustion engine of the vehicle.
