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.

der
Als nachteilig bei bekannten Wasserstofftanks in Kraftfahrzeugen ist es anzusehen, dass sie besonders bei einem hohen Fülldruck eine Wandung ausreichender Stärke oder Dicke benötigen, um die Betriebssicherheit zu gewährleisten. Somit wird auch unter Verwendung von Faserverbundwerkstoffen das Gesamtgewicht eines derartigen Wasserstofftanks in unerwünschter Weise erhöht.When is disadvantageous in known hydrogen tanks in motor vehicles to look at it, especially at a high inflation pressure need a wall of sufficient thickness or thickness, to ensure operational safety. Thus, will also using fiber composites the total weight such a hydrogen tank in an undesirable manner elevated.
Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, einen Wasserstofftank in einem Kraftfahrzeug zu schaffen, dessen Gesamtgewicht bei gleicher Füllmenge oder gleichem Fülldruck verringert ist.outgoing From this prior art, the invention is based on the object to provide a hydrogen tank in a motor vehicle whose Total weight for the same capacity or same filling pressure is reduced.
Diese Aufgabe wird durch einen Wasserstofftank mit den Merkmalen des Anspruchs 1 gelöst, ein entsprechend ausgestattetes Kraftfahrzeug ist in Anspruch 9 angegeben.These Task is by a hydrogen tank with the features of the claim 1 solved, a suitably equipped motor vehicle is specified in claim 9.
Bei einem derart ausgebildeten Wasserstofftank ist ein erstes Tankvolumen mit einem ersten Fülldruck p1 vorzugsweise vollständig von einem zweiten Tankvolumen mit einem zweiten Fülldruck p2 umhüllt oder umschlungen. Dadurch, dass auf die Außenhülle des ersten, inneren Tankvolumens der Fülldruck p2 des äußeren, zweiten Tankvolumens drückt muss diese erste Tankwandung lediglich eine Druckdifferenz zwischen dem zweiten, niedrigeren Fülldruck p2 und dem ersten, höheren Fülldruck p1 auffangen. Daher muss sie nicht in einer derartigen Dicke ausgeführt werden, wie wenn sie den gesamten ersten, höheren Fülldruck p1 gegenüber dem normalen Luftdruck standhalten müsste. Die dünnere Auslegung ergibt eine Materialeinsparung und eine Verringerung des Gesamtgewichts des Wasserstofftanks.In a hydrogen tank formed in this way, a first tank volume having a first filling pressure p 1 is preferably completely enveloped or wrapped around a second tank volume with a second filling pressure p 2 . Due to the fact that the filling pressure p 2 of the outer, second tank volume presses on the outer shell of the first, inner tank volume, this first tank wall only has to absorb a pressure difference between the second, lower filling pressure p 2 and the first, higher filling pressure p 1 . Therefore, it does not have to be made to such a thickness as if it had to withstand the entire first, higher inflation pressure p 1 from the normal air pressure. The thinner design results in a material saving and a reduction of the total weight of the hydrogen tank.
Prinzipiell kann auch eine dritte Schale mit einem dritten Tankvolumen mit einem dritten, noch niedrigeren Fülldruck p3 vorgesehen sein oder noch eine vierte, fünfte oder noch weitere Schale mit jeweils abnehmenden Fülldrücken.In principle, a third shell can also be provided with a third tank volume with a third, even lower filling pressure p 3 or even a fourth, fifth or even further shell, each with decreasing filling pressures.
Im Rahmen der Erfindung ist die Formgebung eines derartig ausgebildeten Wasserstofftanks vom Fachmann in an sich beliebiger Weise wählbar, insbesondere derart, um vorhandene Einbauräume in einem Kraftfahrzeug optimal ausnutzen zu können. Es versteht sich, dass die jeweiligen Tankwandungen der einzelnen, einander umhüllenden Tankvolumina in Abhängigkeit von konkaven, konvexen, geraden oder abgerundeten Formgebungen jeweils in entsprechender Materialstärke ausgeführt sind, um eine Beschädigung oder Zerstörung während des normalen Betriebs zu vermeiden. Bevorzugt weist der Wasserstofftank jedoch eine längliche, im Wesentlichen zylindrische beziehungsweise flaschenförmige Formgebung auf, wobei die mehreren Tankvolumina insbesondere jeweils runde Querschnitte aufweisen.in the The invention is the shape of such a trained Hydrogen tanks selectable by the skilled person in any manner, in particular such, to existing installation spaces in a motor vehicle to be able to exploit optimally. It is understood that the respective tank walls of the individual, each other enveloping Tank volumes depending on concave, convex, straight or rounded shapes each in the appropriate thickness are executed to damage or destruction during normal operation. Preferably However, the hydrogen tank is an elongated, substantially cylindrical or bottle-shaped shaping, wherein the several tank volumes in particular each have round cross-sections.
Es ist ersichtlich, dass das Befüllen beziehungsweise Entleeren des Wasserstofftanks derart erfolgt, dass in allen Tankvolumina eine im Wesentlichen gleichmäßige Druckabnahme erfolgt, so dass insbesondere nicht das äußere, zweite Tankvolumen zuerst vollständig entleert wird und der gesamte erste, höhere Innendruck des ersten Tankvolumens auf der ersten Tankwandung lasten würde. Hierzu ist der Wasserstofftank mit entsprechenden Druck- und Regelventilen ausgestattet und das Befüllen beziehungsweise Entleeren kann von einer Steuerelektronik geregelt werden.It it can be seen that the filling or emptying the hydrogen tank is such that in all tank volumes a substantially uniform pressure decrease is done so that in particular not the outer, second tank volume is first completely emptied and the entire first, higher internal pressure of the first tank volume would load on the first tank wall. This is the hydrogen tank Equipped with appropriate pressure and control valves and the Filling or emptying can by an electronic control system be managed.
Der Vorteil der Erfindung besteht darin, dass bei einem gleichen Tankvolumen durch den mehrschaligen Aufbau in den innen liegenden Schalen mit jeweils höheren Fülldrücken mehr Wasserstoff befüllt werden kann, so dass die Gesamtmenge des in den Wasserstofftank einfüllbaren Wasserstoffs zunimmt, ohne dass das Gesamtgewicht in unerwünschter Weise erhöht werden würde. Außer Wasserstoff können natürlich auch andere gasförmige Betriebsstoffe in einem entsprechend ausgebildeten Tank im Kraftfahrzeug mitgeführt werden.The advantage of the invention is that with the same tank volume through the multi-shell structure in the inner shells with higher filling pressures more hydrogen can be filled, so that the total amount of fillable into the hydrogen tank hydrogen increases without the total weight in an undesirable manner would be increased. Except hydrogen NEN of course, other gaseous fuels are carried in a suitably trained tank in the vehicle.
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.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.
Vorzugsweise erfolgt das Aufbringen der zusätzlichen Verstärkungsfasern in einem an sich bekannten Wickelverfahren.Preferably the application of the additional reinforcing fibers takes place in a known winding method.
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.
Schließlich ist vorgeschlagen, dass der Wasserstofftank zwei miteinander verbundene Tankbehälter umfasst, die beispielsweise T- oder L-förmig angeordnet und miteinander verflanscht sind. Dabei herrscht in einem ersten Tank ein höherer Druck als im anderen, zweiten Tank. Für den Tank niedrigeren Drucks ist ein Regelventil vorgesehen, wobei beim Befüllen zuerst der Niederdruck-Tank befüllt wird, bis dieser seinen Arbeitsdruck erreicht hat. Nachfolgend wird der Tank mit höherem Fülldruck befüllt. Während des Betriebs erfolgt die Entnahme in umgekehrter Reihenfolge.After all It is suggested that the hydrogen tank be two interconnected Tank container includes, for example, arranged T- or L-shaped and are flanged together. It prevails in a first Tank a higher pressure than the other, second tank. For the tank of lower pressure is provided with a control valve, wherein when filling, first fill the low-pressure tank until it has reached its working pressure. Below is the tank is filled with higher filling pressure. During operation, the removal takes place in reverse order.
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.
