Abstract
Ein Druckbehälter (10) zum Speichern von gasförmigem Wasserstoff unter Druck weist einen Liner (12), der einen Innenraum (14) zur Aufnahme des gasförmigen Wasserstoffs definiert, und eine den Liner (12) umgebende Bewicklung (16), die dem Druckbehälter (10) seine Formstabilität verleiht, auf. Um bei einer Entladung des Druckbehälters (10) nach längerer Standzeit ein Austreten von gasförmigem Wasserstoff aus der Bewicklung (16) des Druckbehälters mit hoher zu verhindern, ist die Bewicklung (16) des Druckbehälters (10) zumindest teilweise gasdurchlässig ausgebildet, sodass das den Liner (12) durchdringende Gas kontinuierlich durch die Bewicklung (16) aus dem Druckbehälter (10) entweichen kann.A pressure vessel (10) for storing gaseous hydrogen under pressure comprises a liner (12) defining an interior space (14) for receiving the gaseous hydrogen, and a coil (16) surrounding the liner (12) which communicates with the pressure vessel (10 ) imparts its dimensional stability. In order to prevent leakage of gaseous hydrogen from the winding (16) of the pressure vessel at a discharge of the pressure vessel (10) after a long service life, the winding (16) of the pressure vessel (10) is at least partially gas-permeable, so that the liner (12) penetrating gas continuously through the winding (16) from the pressure vessel (10) can escape.
Description
Die Erfindung betrifft einen Druckbehälter zum Speichern von gasförmigen Medien unter Druck. Sie betrifft insbesondere einen solchen Druckbehälter nach dem Oberbegriff des Anspruches 1 bzw. des Anspruches 5.The The invention relates to a pressure vessel for storing gaseous media under pressure. It concerns in particular Such a pressure vessel according to the preamble of the claim 1 or claim 5.
Solche
gattungsbildenden Druckbehälter, die auch als Composite-Druckbehälter
bezeichnet werden, sind zum Beispiel aus der
Druckbehälter dieser Art werden zum Beispiel als Wasserstoffspeicher in Brennstoffzellensystemen verwendet und können Wasserstoff gasförmig mit mehreren hundert bar Überdruck speichern.pressure vessel of this kind, for example, as hydrogen storage in fuel cell systems used and can be hydrogen gas with store several hundred bar overpressure.
Man hat beobachtet, dass bei einer Entladung solcher Composite-Druckbehälter nach längerer Standzeit gasförmiger Wasserstoff aus der Bewicklung des Druckbehälters mit einer vergleichsweise hohen Rate austritt. Es besteht daher Bedarf an Druckbehältern mit einem verminderten Gefährdungspotenzial durch austretenden Wasserstoff.you has observed that when discharging such composite pressure vessels after prolonged service gaseous hydrogen from the winding of the pressure vessel with a comparatively high rate exits.

Es ist eine Aufgabe der vorliegenden Erfindung, einen Composite-Druckbehälter der eingangs genannten Art zu schaffen, der eine Gefährdung der Umgebung durch mit zu hohen Raten austretenden Gasen ausschließt.It It is an object of the present invention to provide a composite pressure vessel to create the type mentioned, the danger excludes the environment by exiting at high rates gases.
Diese Aufgabe wird gelöst, indem ein schlagartiger Austritt von gasförmigen Medien in hohen Raten bei einer Entladung des Druckbehälters nach längerer Standzeit dadurch verhindert wird, dass das durch den Liner hindurch tretende gasförmige Medium kontinuierlich und damit in niedrigen Raten vom Druckbehälter in die Umgebung abgegeben wird. Es wird also vermieden, dass sich das durch den Liner hindurch tretende Gas in Taschen zwischen dem Liner und der Bewicklung sammeln und dann bei einer Entladung des Druckbehälters aufgrund der Trennung zwischen Liner und Bewicklung schlagartig und in hohen Raten aus dem Druckbehälter in die Umgebung ausströmt.These Task is solved by a sudden exit of gaseous media in high rates during a discharge of the Pressure vessel after prolonged life thereby prevents the passing through the liner gaseous Medium continuously and thus in low rates from the pressure vessel is discharged into the environment. So it's avoided that the gas passing through the liner into pockets between the Gather liners and wrapping and then unload them Pressure vessel due to the separation between liner and Wrapping abruptly and at high rates from the pressure vessel flows into the environment.
Gemäß einem ersten Aspekt der Erfindung enthält ein Druckbehälter zum Speichern von gasförmigen Medien unter Druck einen Liner, der einen Innenraum zur Aufnahme eines gasförmigen Mediums definiert, und eine den Liner umgebende Bewicklung, die dem Druckbehälter eine Formstabilität verleiht. Erfindungsgemäß ist die Bewicklung des Druckbehälters zumindest teilweise gasdurchlässig ausgebildet, sodass das den Liner durchdringende Gas durch die Bewicklung aus dem Druckbehälter entweichen kann.According to one First aspect of the invention includes a pressure vessel for storing gaseous media under pressure Liner, which has an interior to accommodate a gaseous Medium defines, and a winding surrounding the liner, the gives the pressure vessel a dimensional stability. According to the invention the winding of the pressure vessel at least partially gas permeable formed so that the gas penetrating the liner through the winding can escape from the pressure vessel.
Durch diesen Aufbau des Druckbehälters mit einer zumindest teilweise gasdurchlässigen Bewicklung wird erreicht, dass das durch den Liner hindurch tretende Gas kontinuierlich und mit niedrigen Raten vom Druckbehälter an die Umgebung abgegeben werden kann. Auf diese Weise wird verhindert, dass das durch den Liner hindurch tretende Gas zwischen Liner und Bewicklung angesammelt und dann bei einer Entladung des Druckbehälters schlagartig und in hohen Raten vom Druckbehälter in die Umgebung abgegeben wird.By this construction of the pressure vessel with an at least partially Gas permeable winding is achieved by that The gas passing through the liner is continuous and low Rates are discharged from the pressure vessel to the environment can. This will prevent that from happening through the liner passing through gas accumulated between liner and winding and then abruptly upon discharge of the pressure vessel and discharged in high rates from the pressure vessel into the environment becomes.
In einer Ausgestaltung der Erfindung ist die Bewicklung des Druckbehälters zumindest teilweise porös ausgebildet. Beispielsweise ist die Bewicklung des Druckbehälters aus einem Fasermaterial gebildet, welches mit einem Harzmaterial fixiert ist, wobei das Harzmaterial im ausgehärteten Zustand zumindest teilweise porös ist.In An embodiment of the invention is the winding of the pressure vessel at least partially porous. For example the winding of the pressure vessel made of a fiber material formed, which is fixed with a resin material, wherein the Resin material in the cured state at least partially is porous.
Alternativ oder zusätzlich ist die Bewicklung des Druckbehälters an vorbestimmten Stellen mit Bohrungen versehen, welche die Innenseite der Bewicklung mit ihrer Außenseite verbinden.alternative or additionally, the winding of the pressure vessel provided at predetermined locations with holes which the inside connect the winding with its outside.
In einer weiteren Ausgestaltung der Erfindung ist die Bewicklung des Druckbehälters auf ihrer Außenseite mit einer Beschichtung (z. B. Lackschicht) versehen, welche zumindest in den gasdurchlässigen Bereichen der Bewicklung ebenfalls gasdurchlässig ausgebildet ist.In a further embodiment of the invention, the winding of the Pressure vessel on its outside with a Coating (eg lacquer layer) provided, which at least in the Gas permeable areas of the winding also gas permeable is trained.
Gemäß einem zweiten Aspekt der Erfindung enthält ein Druckbehälter zum Speichern von gasförmigen Medien unter Druck einen Liner, der einen Innenraum zur Aufnahme eines gasförmigen Mediums definiert, und eine den Liner umgebende Bewicklung, die dem Druckbehälter eine Formstabilität verleiht. Erfindungsgemäß ist zwischen dem Liner und der Bewicklung eine gasdurchlässige Zwischenschicht vorgesehen, die in wenigstens einem Bereich mit der Außenseite der Bewicklung verbunden ist, sodass das den Liner durchdringende Gas durch die Zwischenschicht aus dem Druckbehälter entweichen kann.According to a second aspect of the invention, a pressure vessel for storing gaseous media under pressure includes a liner having an interior for receiving a gaseous medium defined, and a winding surrounding the liner, which gives the pressure vessel a dimensional stability. According to the invention, a gas-permeable intermediate layer is provided between the liner and the winding, which is connected in at least one area with the outside of the winding, so that the gas penetrating the liner can escape from the pressure vessel through the intermediate layer.
Durch diesen Aufbau des Druckbehälters mit einer zumindest teilweise gasdurchlässigen Zwischenschicht zwischen Liner und Bewicklung wird erreicht, dass das durch den Liner hindurch tretende Gas kontinuierlich und mit niedrigen Raten vom Druckbehälter an die Umgebung abgegeben werden kann. Auf diese Weise wird verhindert, dass das durch den Liner hindurch tretende Gas zwischen Liner und Bewicklung gesammelt und dann bei einer Entladung des Druckbehälters schlagartig und in hohen Raten vom Druckbehälter in die Umgebung abgegeben wird.By this construction of the pressure vessel with an at least partially gas-permeable intermediate layer between liner and winding it is achieved that the gas passing through the liner is continuous and at low rates from the pressure vessel to the environment can be delivered.
