Abstract: The technology disclosed by the invention relates to a pressure vessel system for a motor vehicle for storing fuel, comprising a plurality of pressure vessels (100) that are combined to a pressure vessel assembly (10), the pressure vessels (100), when mounted, being arranged substantially in parallel relative to each other, and the pressure vessels (100) being fluidically interconnected via a common fuel line (200).

Abstract: A device for monitoring the use of a pressure container system of a piece of equipment, such as a motor vehicle, is designed to ascertain equipment-side usage data relating to previous use of the pressure container system. The device is additionally designed to compare the equipment-side usage data with equipment-external usage data relating to the previous use of the pressure container system and to initiate one or more measures relating to further use of the pressure container system on the basis of the comparison.

Abstract: A method for enabling a fuel cell system includes the steps of: i) detecting a pressure value, which is indicative of the pressure within a section of the anode sub-system, wherein the section begins downstream of a pressure reducer; ii) relieving the pressure of the section during a pressure relief time interval, if the pressure value is greater than a pressure limit value and a release request is present; and then iii) enabling the fuel cell system if the pressure value in the section after the pressure relief is less than the pressure limit value.
