Pressure Vessel for Storing Gaseous Media Under Pressure

Abstract

A pressure vessel for the storage of pressurized gaseous hydrogen includes a liner which defines an interior for the accommodation of the gaseous hydrogen and a wrapping encompassing the liner which gives the pressure vessel its dimensional stability. In order to prevent a discharge of gaseous hydrogen from the wrapping of the pressure vessel at a high rate if the pressure vessel is discharged after a prolonged downtime, the wrapping of the pressure vessel is designed to be at least partially gas-permeable, so that the gas penetrating through the liner can escape continuously through the wrapping of the pressure vessel.

1 . A pressure vessel for storing pressurised gaseous media, comprising:
 a liner that defines an interior for accommodation of a gaseous medium; and   a wrapping encompassing the liner that gives the pressure vessel dimensional stability,   wherein the wrapping of the pressure vessel is at least partially gas-permeable, so that the gaseous medium penetrates through the liner and escapes from the pressure vessel through the wrapping.   
     
     
         2 . The pressure vessel according to  claim 1 , wherein the wrapping of the pressure vessel is at least partially porous and/or provided with holes ( 34 ) which connect the inside of the wrapping to its outside. 
     
     
         3 . The pressure vessel according to  claim 1 , wherein the wrapping of the pressure vessel is made of a fibrous material bound with a resin material, the resin material being at least partially porous in the set state. 
     
     
         4 . The pressure vessel according to  claim 1 , wherein the wrapping of the pressure vessel is provided with a coating on its outside, which is gas-permeable at least in the gas-permeable regions of the wrapping. 
     
     
         5 . A pressure vessel for storing pressurised gaseous media, comprising:
 a liner that defines an interior for accommodation of a gaseous medium; and   a wrapping encompassing the liner that gives the pressure vessel dimensional stability,   wherein a gas-permeable intermediate layer is connected to the outside of the wrapping in at least one region and is provided between the liner and the wrapping, so that the gaseous medium penetrates through the liner and escapes from the pressure vessel through the intermediate layer.   
     
     
         6 . The pressure vessel according to  claim 5 , wherein the intermediate layer is at least partially porous. 
     
     
         7 . The pressure vessel according to  claim 5 , wherein a gas treatment device is provided in a connecting region between the intermediate layer and the outside of the wrapping. 
     
     
         8 . The pressure vessel according to  claim 7 , wherein the gas treatment device comprises an oxidising catalyst. 
     
     
         9 . The pressure vessel according to  claim 7 , wherein the gas treatment device is produced by impregnating the intermediate layer with a gas treatment medium. 
     
     
         10 . The pressure vessel according to  claim 7 , wherein the connecting region between the intermediate layer and the outside of the wrapping is provided in a region of a neck of the pressure vessel. 
     
     
         11 . The pressure vessel according to  claim 7 , wherein the connecting region between the intermediate layer and the outside of the wrapping is provided in a region of a filling and/or discharge opening of the pressure vessel. 
     
     
         12 . The pressure vessel according to  claim 2 , wherein the wrapping of the pressure vessel is provided with a coating on its outside, which is gas-permeable at least in the gas-permeable regions of the wrapping. 
     
     
         13 . The pressure vessel according to  claim 3 , wherein the wrapping of the pressure vessel is provided with a coating on its outside, which is gas-permeable at least in the gas-permeable regions of the wrapping. 
     
     
         14 . The pressure vessel according to  claim 6 , wherein a gas treatment device is provided in a connecting region between the intermediate layer and the outside of the wrapping. 
     
     
         15 . The pressure vessel according to  claim 8 , wherein the gas treatment device is produced by impregnating the intermediate layer with a gas treatment medium. 
     
     
         16 . The pressure vessel according to  claim 8 , wherein the connecting region between the intermediate layer and the outside of the wrapping is provided in a region of a neck of the pressure vessel. 
     
     
         17 . The pressure vessel according to  claim 9 , wherein the connecting region between the intermediate layer and the outside of the wrapping is provided in a region of a neck of the pressure vessel. 
     
     
         18 . The pressure vessel according to  claim 8 , wherein the connecting region between the intermediate layer and the outside of the wrapping is provided in a region of a filling and/or discharge opening of the pressure vessel. 
     
     
         19 . The pressure vessel according to  claim 9 , wherein the connecting region between the intermediate layer and the outside of the wrapping is provided in a region of a filling and/or discharge opening of the pressure vessel. 
     
     
         20 . The pressure vessel according to  claim 10 , wherein the connecting region between the intermediate layer and the outside of the wrapping is provided in a region of a filling and/or discharge opening of the pressure vessel.
