The invention relates to a compressed gas storage unit (1) for mobile applications, in particular for storing hydrogen on board a vehicle, comprising at least one metal storage housing (2) which delimits a storage volume (3) that can be filled with compressed gas, as well as at least one temperature- and/or pressure-sensitive overload valve (4) arranged on the storage housing (2). According to the invention, the storage housing (2) or the compresses gas storage unit (1) is surrounded by a heat protection shield (5) at least in regions, preferably releasing the at least one overload valve (4). The invention also relates to a vehicle comprising a compressed gas storage unit (1) according to the invention for storing hydrogen.

A motor vehicle has at least one pressure vessel for storing storage medium, preferably fuel, at least one pressure relief device for pressure relief of the at least one pressure vessel, and at least one opening through which storage medium flows out during a pressure relief.

A tank for containing pressurized hydrogen for a fuel cell vehicle, comprising at least one fuel tank comprising a wall configured to delimit an internal volume for containing said pressurized hydrogen, said tank comprising safety means configured to chemically neutralize said pressurized hydrogen according to a pre-established condition.

A service device for a pressure vessel system of a motor vehicle includes a service-device-side refueling coupling part which is connectable to a motor-vehicle-side refueling coupling part of the motor vehicle and a controller for activating the pressure vessel system. A method for the service of the pressure vessel system includes producing a connection between the service device and the pressure vessel system and activating the pressure vessel system by the service device.

A high pressure container unit includes a container body configured to store high pressure gas, a case storing the container body inside the case, a pipe connected with the container body and extending to an outside of the case, a closing member that is configured to close the pipe and allow the high pressure gas stored in the container body to be discharged from the pipe when a given condition is satisfied, and a ventilation mechanism that discharges air inside the case to the outside of the case with use of pressure of the discharged high pressure gas when the given condition is satisfied.

A pressure vessel for storing may have a connection piece for forming a fluid connection between the fuel storage volume V of the pressure vessel and an energy converter of a motor vehicle. At least part of the connection piece may extend out of the pressure vessel. An outer surface of the connection piece may have a sealing face and a curved fastening face. The sealing face may be designed to seal off the fluid connection between the pressure vessel and a fuel-conducting section of the motor vehicle. The fastening face may be provided for fastening the pressure vessel to at least one body attachment element.

A boil-off management system for a cryotank includes a boil-off conduit which is fluidically connectable to a cryotank via a boil-off valve. The boil-off management system further includes an air feed conduit and a mixing chamber for mixing a first medium (e.g., hydrogen) flowing in through the boil-off conduit with a second medium (e.g., air and/or oxygen) flowing in through the air feed conduit. A catalytic converter is arranged downstream of the mixing chamber and an outlet downstream of the catalytic converter. At least one enrichment apparatus is provided and configured to temporarily increase the proportion of the first medium flowing in through the boil-off conduit in relation to the second medium flowing in through the air feed conduit at the catalytic converter.

A cylinder assembly for a hydrogen-powered fuel cell motor vehicle system which has a plurality of cylinders and a first thermal safety device is provided. The first thermal safety device has a trigger mechanism and a plurality of trigger wires made of a shape memory material. Each trigger wire of the plurality of trigger wires extends along a straight trigger axis and is connected to the trigger mechanism and to a fixed backing part. The trigger axes are intersecting with each other.

The gas supply system of this invention is furnished with a cylinder apparatus having a pneumatic valve that supplies process gas to a process chamber, and a solenoid valve that opens or closes said pneumatic valve by supplying or stopping the flow of valve actuating gas to said pneumatic valve; and a gas supply control apparatus that controls the actuation of the solenoid valve. In addition, said gas supply control apparatus comprises a main controller that controls the actuation of said solenoid valve during normal operation, and a sub-controller that senses an abnormal state of said main controller and if an abnormality is sensed, controls the actuation of said solenoid valve instead of said main controller.

One example of a safety withdrawal system includes a cryogenic container, a withdrawal line and an economizer situated between the withdrawal line and the cryogenic container for withdrawing cryogenic fluid in liquid phase and gas phase, and the economizer is configured as an electric economizer having two controllable valves that are respectively currentless closed, which each may block the withdrawal of the liquid phase or the gas phase from the cryogenic container. The safety withdrawal system further includes an emergency stop off-switch that may be manually actuated, which is connected to the two currentless closed valves of the electric economizer and is configured to simultaneously block the withdrawal of cryogenic fluid by both valves upon actuation.
