Pressure vessel system for a motor vehicle

A pressure vessel system having at least one pressure vessel for a motor vehicle, comprising:

• an extraction line that connects to the pressure vessel, wherein the extraction line has a connection point;
• a pressure reducing device along the extraction line upstream from the connection point and downstream from the pressure vessel;
• and
• a connection line that leads to a consumer, wherein the connection line connects to the connection point, wherein the consumer is an anode space of a fuel cell stack and the connection line is an anode supply line leading to an anode inlet of the fuel cell stack,
• a second connection line that leads to an extraction or supply device, wherein
• the connection point of the extraction line comprises a first coupling part of a quick coupling,
• a second coupling part of the quick coupling arranged on the connection line connects to the first coupling part,
• the first coupling part comprises a check valve which closes the extraction line when the second coupling part is uncoupled,
• the second coupling part comprises a check valve which closes the connection line when the first coupling part is uncoupled, and
• a third coupling part connected to the extraction or supply device by the second connection line is attachable to the first coupling part or the second coupling part.
