Abstract
Description
Die Erfindung bezieht sich auf einen Wasserstofftank in einem Kraftfahrzeug.The The invention relates to a hydrogen tank in a motor vehicle.
Moderne Antriebssysteme für Kraftfahrzeuge basieren auf dem Einsatz von gasförmigem Wasserstoff als Energieträger. Hierzu wird der Wasserstoff in einem Wasserstofftank mit einem bis zu 700fachen Überdruck im Kraftfahrzeug mitgeführt. Derartige Wasserstofftanks sind bisher als Stahlflaschen mit bis zu 200fachem Überdruck eingesetzt worden. Eine Wandung des Wasserstofftanks kann auch für einen höheren Fülldruck aus einem Faserverbundwerkstoff mit beispielsweise Glas- und/oder Kohlenstofffasern bestehen.modern Drive systems for motor vehicles are based on the use of gaseous hydrogen as an energy source. For this, the hydrogen in a hydrogen tank with a to entrained 700 times overpressure in the motor vehicle. such Hydrogen tanks are so far as steel cylinders with up to 200 times overpressure been used. A wall of the hydrogen tank can also be used for a higher filling pressure of a fiber composite material consist for example with glass and / or carbon fibers.
Derartige Wasserstofftanks verfügen über Zu- und Ableitungen zum Befüllen beziehungsweise zur Versorgung eines Antriebssystems mit dem benötigen Wasserstoff sowie über ein Überdruckventil. Ein Wasserstofftank wird mit geeigneten Haltevorrichtungen an einer Rohbaustruktur beziehungsweise einer Karosserie eines Kraftfahrzeugs befestigt, wobei der Wasserstofftank in seiner äußeren Formgebung an einen vorhandenen Einbauraum der Rohbaustruktur angepasst sein kann.such Hydrogen tanks have inlets and outlets for filling or for supplying a drive system with the required hydrogen as well as a pressure relief valve. One Hydrogen tank is attached to a suitable holding devices Shell structure or a body of a motor vehicle attached, with the hydrogen tank in its outer Shape adapted to an existing installation space of the bodyshell structure can be.
Ein
derartiger Druckbehälter, insbesondere zum Mitführen
von Wasserstoff, ist aus der
Als nachteilig bei den bekannten Wasserstofftanks ist es anzusehen, dass ein großes Tankvolumen häufig nicht in einen vorhandenen Einbauraum in einem Kraftfahrzeug eingepasst werden kann.When it is disadvantageous in the known hydrogen tanks, that a large tank volume is often not in one existing installation space can be fitted in a motor vehicle.
Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, einen Wasserstofftank anzugeben, der eine optimale Einbauraumausnutzung ermöglicht, insbesondere in einem Kraftfahrzeug. Weiterhin soll ein entsprechend ausgestattetes Kraftfahrzeug angegeben werden.outgoing From this prior art, the invention is based on the object indicate a hydrogen tank, the optimal installation space utilization allows, especially in a motor vehicle. Farther should be specified a suitably equipped motor vehicle.
Diese Aufgaben werden durch einen Wasserstofftank mit den Merkmalen des Anspruchs 1 beziehungsweise durch ein Kraftfahrzeug mit den Merkmalen des Anspruchs 8 gelöst.These Tasks are performed by a hydrogen tank with the characteristics of the Claim 1 or by a motor vehicle with the features of claim 8 solved.
Ein derartiger Wasserstofftank weist zwei miteinander verbundene aber räumlich getrennte separate Tankbehälter auf, die vorzugsweise jeweils für sich gesehen eine längliche Formgebung aufweisen. Die beiden Tankbehälter sind derart miteinander verbunden, dass sie nach Art eines „T” oder „L” angeordnet sind. In den beiden Tankbehältern kann ein gleicher Fülldruck herrschen, insbesondere wenn sie unmittelbar miteinander verbunden sind oder ein jeweils unterschiedlicher Fülldruck, wie im Folgenden beschrieben.One such hydrogen tank has two interconnected but spatially separated separate tank containers, preferably each considered an elongated Shaping have. The two tank containers are like that interconnected, that they arranged in the manner of a "T" or "L" are. In the two tank containers, an equal filling pressure prevail, especially if they are directly connected are or a different filling pressure, such as described below.
Prinzipiell können auch ein oder mehrere weitere Tankbehälter vorgesehen sein, die insgesamt den Wasserstofftank bilden. Ebenso können auch zwei beispielsweise im Wesentlichen gleichartig ausgeformte Tankbehälter zueinander parallel angeordnet sein und über entsprechende Druckleitungen, Regelventile und Flansche miteinander verbunden werden.in principle can also have one or more other tank containers be provided, which together form the hydrogen tank. As well For example, two may be substantially similar molded tank container arranged parallel to each other be and via appropriate pressure lines, control valves and flanges are connected together.
Vorzugsweise werden Anschlussstücke beziehungsweise Flansche bei im Wesentlichen länglichen und zylindrischen Tankbehältern im Bereich der jeweiligen Tankendstücke angeordnet sein.Preferably are fittings or flanges in im Essentially elongated and cylindrical tank containers be arranged in the region of the respective tank end pieces.
Die beiden Tankbehälter können unmittelbar aneinander anschließend ausgebildet sein oder in geringem Abstand mit einer Druckleitung verbunden werden.The Both tanks can be directly adjacent to each other be subsequently formed or at a small distance be connected to a pressure line.
Im Rahmen der Erfindung ist es mit umfasst, dass der Wasserstofftank in Form eines einzigen, durchgehenden Tankbehälters ausgebildet ist, der allerdings eine T- oder L-Form aufweist.in the Within the scope of the invention, it is included with that of the hydrogen tank formed in the form of a single, continuous tank is, however, has a T or L shape.
Der Vorteil der Erfindung besteht darin, dass eine individuelle Anpassung an durch die Fahrzeugkonstruktion vorgegebene Einbaumaße möglich ist. Dabei können dem Wasserstofftank an sich beliebige Formgebungen verliehen werden, wobei die jeweiligen Wandungen der Tankbehälter in Abhängigkeit von konvexen, konkaven, geraden oder gekrümmten Formgebungen jeweils mit ausreichenden Wandstärken ausgeführt sind, um die Festigkeit und Betriebssicherheit auch während eines Fahrtbetriebs zu gewährleisten.Of the Advantage of the invention is that an individual adaptation to specified by the vehicle design installation dimensions is possible. This can be the hydrogen tank in itself arbitrary forms are lent, whereby the respective Walls of the tank container depending on convex, concave, straight or curved shapes each carried out with sufficient wall thicknesses are to maintain the strength and reliability even during to ensure a driving operation.
Weiterhin ist vorgeschlagen, dass in den zumindest zwei miteinander verbundenen Tankbehältern jeweils ein unterschiedlicher Fülldruck herrscht. Hierzu sind die beiden separaten Tankbehälter über einen Flansch, eine Druckleitung sowie ein Regelventil zur Druckregulierung miteinander verbunden. Beim Entleeren des Wasserstofftanks wird das benötigte Wasserstoffgas aus dem Tank mit niedrigerem Druck entnommen, wobei gleichzeitig aus dem Tank mit höherem Fülldruck Gas in den Tank mit niedrigerem Druck solange nachströmt, bis auch der Tank mit ursprünglich höherem Fülldruck praktisch entleert ist. Beim Befüllen wird zuerst der Tank mit niedrigerem Fülldruck befüllt, bis dieser seinen Arbeitsdruck erreicht hat, und nachfolgend der Tank mit höherem Druck oder umgekehrt.Furthermore, it is proposed that in each case a different filling pressure prevails in the at least two interconnected tank containers. For this purpose, the two separate tank containers via a flange, a pressure line and a control valve for pressure regulation are interconnected. When emptying the hydrogen tank, the required hydrogen gas is withdrawn from the tank at lower pressure, while at the same time from the tank with higher filling pressure gas in the tank with low The pressure continues to flow until the tank is virtually emptied with originally higher filling pressure. When filling, the tank is first filled with lower filling pressure until it has reached its working pressure, and subsequently the tank with higher pressure or vice versa.
In einer weiteren Ausgestaltung weist der Wasserstofftank einen mehrschaligen Aufbau auf. Das bedeutet, dass mehrere in sich abgeschlossene Tankvolumina jeweils einander umhüllend angeordnet sind. Dabei herrscht im innersten Tankvolumen der höchste Fülldruck, der jeweils nach Außen hin abnimmt. Bei einer derartigen Anordnung verschiedener Tanks ineinander muss eine Wandung des innersten Tankes nicht derart dickwandig ausgelegt werden, dass sie den vollständigen Unterschied zwischen Normaldruck und dem Druck im Inneren aufnehmen muss, sondern lediglich die Druckdifferenz zum umgebenenden Tankvolumen. Somit kann jeweils Material bei der Auslegung der verschiedenen Tankwandungen eingespart werden.In In another embodiment, the hydrogen tank has a multi-shell Build up. This means that several self-contained tank volumes are each arranged enveloping each other. It prevails in the innermost tank volume the highest filling pressure, which decreases towards the outside. In such a Arrangement of different tanks into each other must have a wall of the innermost Tankes are not designed to be so thick-walled that they are the complete Record difference between normal pressure and the pressure inside must, but only the pressure difference to the surrounding tank volume. Thus, in each case material in the design of the various tank walls be saved.
Die einzelnen schalenartigen Tankvolumina können jeweils eine im Wesentlichen ähnliche Querschnittsform aufweisen, prinzipiell können diese aber auch voneinander abweichen, beispielsweise ein ungefähr rundes, zylindrisches inneres Tankvolumen und ein dieses umhüllendes, im Querschnitt gesehen ungefähr rechteckiges äußeres, zweites Tankvolumen.The each shell-like tank volumes can each one have substantially similar cross-sectional shape, in principle But these can also differ, for example an approximately round, cylindrical inner tank volume and an enveloping one, seen in cross-section approximately rectangular outer, second tank volume.
Zur Verstärkung können zwischen den Wandungen verschiedener Tankvolumina jeweils ein oder mehrere Verstärkungsstege vorgesehen sein, die auch jeweils einstückig mit den Tankwandungen ausgeführt sein können. Vorzugsweise erstrecken sich derartige Verstärkungsstege über die gesamte Länge des Wasserstofftanks, um eine durchgehende Verstärkung zu erhalten.to Reinforcement can be between the walls of different Tank volumes each one or more reinforcing webs be provided, which also each integral with the tank walls can be executed. Preferably extend such reinforcing webs over the entire Length of the hydrogen tank to provide a continuous reinforcement to obtain.
Als Materialien für die verschiedenen Tankwandungen kommen unter anderem metallische Werkstoffe in Frage, bevorzugt sind diese Wandungen jedoch aus einem Faserverbundwerkstoff hergestellt, dessen Festigkeitswerte in Abhängigkeit des gewählten Kunststoffmaterials beziehungsweise der Art und Menge der verwendeten Fasern wie Glasfasern, Kohlefasern und/oder metallischer Fasern vom Fachmann gewählt werden kann.When Materials for the different tank walls come Among other metallic materials in question, these are preferred But walls made of a fiber composite material whose Strength values depending on the selected Plastic material or the type and amount of used Fibers such as glass fibers, carbon fibers and / or metallic fibers can be selected by the expert.
Zur Herstellung eines derartigen Wasserstofftanks aus einem Faserverbundwerkstoff ist vorgeschlagen, dass dieser in einem Autoklaven unter Überdruck ausgehärtet wird. Durch den erhöhten Außendruck während des Aushärtens wird der Wandung aus dem Faserverbundwerkstoff eine Eigenspannung verliehen, die beim Befüllen des Wasserstofftanks, vorzugsweise mit Wasserstoffgas, zunächst mit einem ersten Innendruck ausgeglichen werden muss, um einen spannungsfreien Zustand in der Tankwandung zu erhalten. Nachfolgend wird der Innendruck auf den gewünschten Fülldruck erhöht, beispielsweise 700facher Überdruck. Dabei ist der tatsächlich nach Außen wirkende Druck auf die Tankwandung aber kleiner als der 700fache atmosphärischer Überdruck und zwar um den Betrag der Vor oder Eigenspannung. Somit kann die Wandung des Wasserstoffbehälters dünner ausgeführt werden, da nicht der vollständige Überdruck aufgefangen werden muss.to Production of such a hydrogen tank made of a fiber composite material It is proposed that this in an autoclave under pressure is cured. Due to the increased external pressure during curing, the wall is removed from the Fiber composite imparted a residual stress during filling the hydrogen tank, preferably with hydrogen gas, first must be balanced with a first internal pressure to a tension-free Condition to get in the tank wall. Subsequently, the internal pressure increased to the desired filling pressure, for example 700x overpressure. It is actually external pressure on the tank wall but smaller as the 700-fold atmospheric overpressure and although by the amount of pre or residual stress. Thus, the wall can of the hydrogen tank made thinner because not the complete overpressure is absorbed must become.
Zur weiteren Erhöhung der Stabilität können nach dem Aushärtevorgang weitere Verstärkungsfasern unter einer definierten Vorspannung aufgebracht werden. Damit wird zwar die Dicke der Wandung und das Gesamtgewicht des Wasserstofftanks erhöht, jedoch kann der Fülldruck entsprechend ebenfalls erhöht werden. Vorzugsweise erfolgt das Aufbringen der zusätzlichen Verstärkungsfasern in einem an sich bekannten Wickelverfahren ebenso wie das Herstellen des Tankbehälters selbst.to further increase in stability can after the curing process further reinforcing fibers be applied under a defined bias. This will be while increasing the thickness of the wall and the total weight of the hydrogen tank, However, the filling pressure can be increased accordingly become. Preferably, the application of the additional takes place Reinforcing fibers in a known winding method as well as the manufacture of the tank itself.
Weiterhin kann ein Liner beziehungsweise eine gasdichte Schicht oder Beschichtung nicht auf einer Tankinnenseite angebracht sein sondern der Liner wird zumindest teilweise in die Wandung einlaminiert. Somit wird insbesondere für nicht runde Tanks eine zusätzliche Verstärkung erhalten.Farther may be a liner or a gas-tight layer or coating not on a tank inside be attached but the liner is at least partially laminated into the wall. Thus, will especially for non-round tanks an additional Gain received.
Es versteht sich, dass der Wasserstofftank hinsichtlich seiner mechanischen Eigenschaften derart ausgelegt ist, dass er bei der Betankung beziehungsweise der Entleerung während des Betriebs sowie unter verschiedenen Temperatureinflüssen maßhaltig ist, um insbesondere den störungsfreien Einsatz im Kraftfahrzeug zu gewährleisten.It It is understood that the hydrogen tank in terms of its mechanical Characteristics is designed such that it during refueling or emptying during operation as well as under different conditions Temperature influences is dimensionally stable, in particular to ensure trouble-free use in the vehicle.
Zum Einbau des Wasserstofftanks im Kraftfahrzeug ist vorgeschlagen, dass dieser selbst als tragendes Element der Rohbaustruktur des Kraftfahrzeugs ausgebildet ist. Das bedeutet, dass er zur Stabilität einer Rohkarosse des Kraftfahrzeugs beiträgt und gegebenenfalls weitere Komponenten insbesondere der Karosse des Kraftfahrzeugs an dem Wasserstofftank befestigt sein können. Es versteht sich, dass der Wasserstofftank beziehungsweise dessen Wandung in einer ausreichenden Wandstärke ausgelegt ist, um die statischen und dynamischen Kräfte, insbesondere während des Fahrtbetriebs, aufnehmen zu können.To the Installation of the hydrogen tank in the motor vehicle is proposed that this itself as a supporting element of the bodyshell structure of Motor vehicle is formed. That means he's about stability contributes a body of the motor vehicle and optionally other components, in particular the body of the motor vehicle can be attached to the hydrogen tank. It understands itself, that the hydrogen tank or its wall in a sufficient wall thickness is designed to prevent the static and dynamic forces, especially during the Driving operation to record.
Im Vorhergehenden wurde die Erfindung im Wesentlichen im Zusammenhang mit dem Einsatz eines derartigen Wasserstofftanks in einem Kraftfahrzeug beschrieben. Es ist jedoch ersichtlich, dass ein derartiger Wasserstofftank auch auf allen anderen Gebieten der Technik einsetzbar ist, beispielsweise als stationärer Vorratsbehälter für eine Brennstoffzelle zur Energieerzeugung.in the The foregoing has been essentially related to the invention with the use of such a hydrogen tank in a motor vehicle described. However, it is apparent that such a hydrogen tank can also be used in all other fields of technology, for example as stationary storage container for one Fuel cell for energy production.
