Embodiment Construction

[0021] figure 1A pressure vessel system disclosed herein is shown. The pressure vessel system is here connected to the fuel cell stack 210 of the fuel cell system. For simplicity, other components of the fuel cell system and the pressure vessel system are omitted. In this case, the shut-off valve 120 is arranged directly at the end 110 of the pressure vessel 100 . The block valve 120 is a valve that can be controlled electrically. The current flows to the isolating valve 120 via an electrical circuit 300 , not fully shown. As long as current flows through the coil of the block valve 120, the block valve 120 is opened. If the circuit is now interrupted, for example by operating an ignition key (not shown), the isolating valve 120 is closed. This only happens when the motor vehicle is parked after running. Furthermore, a safety switch 310 is provided here, which can additionally interrupt the power supply via the circuit 300 to the magnet of the shut-off valve 120 . Safet...

Abstract

The technology disclosed herein relates to a pressure vessel system for an automotive vehicle. The system comprises: 1) at least one pressure vessel (100) for storing fuel, wherein the pressure vessel system has an isolating valve (120) configured to disconnect said pressure vessel from at least one a fluid connection (200) between a fuel gas consumer (210); and 2) at least one safety switch (310), wherein the safety switch (310) is configured to interrupt the flow to said shut-off valve (120) feed.

Description

technical field [0001] The technology disclosed here relates to a motor vehicle with a fuel cell system and a pressure vessel system, a pressure vessel system for a motor vehicle, and a method for interrupting a fluid connection. Background technique [0002] Motor vehicles with fuel cell systems are known per se and are also referred to as fuel cell electric vehicles (FCEV). Flammable fuel gases such as hydrogen are used in such systems. Currently, there is no possibility to shut down the fuel system in commercial enterprises / institutions (ie workshops, logistics, exhibitions, etc.). In known solutions, the anode subsystem carrying the fuel gas is switched off only when the ignition of the motor vehicle is switched off. For example, in the 2014 standard proposal ECE / TRANS / WP.29 / 2014 / 78 "Proposal for a new Regulation on hydrogen and fuel cell vehicles (HFCV)" (proposal on new regulations on hydrogen fuel cell vehicles): Partition The valves - also called "shut off valves"...
