The invention relates in particular to an energy unit () for producing an operating material on board a vehicle, comprising a fuel cell unit () with at least one fuel cell () and a mobile storage unit (), which is formed separately from the fuel cell unit (), with a store () for storing at least one energy source necessary for operation of the fuel cell unit (). The mobile storage unit () and the fuel cell unit () can be coupled with one another, wherein, in the state coupled to one another, at least one first terminal () of the mobile storage unit () is connected to a corresponding second terminal () of the fuel cell unit () in such a way that at least the at least one energy source can be supplied from the store () to the fuel cell ().

In order to relieve the power supply system of commercial aircraft of one absolutely essential load, specifically a galley with heating and cooling appliances, the appliances are provided with at least one autonomous power supply device which can be handled without any problems and is installed in a galley trolley () of standardized dimensions, preferably with a fuel cell () together with its fuel tanks () and voltage converters () in order to be replaced at the same time by catering lifting loaders in the course of galley supply and disposal. Instead of or in addition thereto, an autonomous, mobile power supply unit such as this can also be installed in one of the standardized baggage or cargo containers for accommodation in the cargo bay of the aircraft, and then in particular also to feed electrical heating and cooling appliances in other containers.

A pressure equalizing system () having two variable volume elements which interact with one another via a separating medium which can be deformed or can be moved as a function of the pressure difference, with a constant total volume, is positioned upstream of a fuel cell () in order to feed the fuel cell () with its raw-material gases (H, O). A pressure equalizing container () can be provided for this purpose, which is subdivided into two chambers (H,O) by a separating wall () which can be deformed or can be moved as a function of the pressure difference; alternatively, two chambers (H,O) are connected to one another by an equalizing channel () with a solid or liquid separating medium which can be moved therein as a function of the pressure difference. If the raw-material gas pressures are different, the separating medium is moved towards the chamber () with the lower gas pressure until a pressure equilibrium is achieved as a consequence of the corresponding change in the volume elements on both sides of the separating medium. In the fuel cell () which is fed from the chambers (), its membrane (), which is susceptible to fracture, therefore no longer has a destruction-critical dynamic pressure difference applied to it, without having to take control measures for this purpose in feed fittings for the raw-material gases.

A method of providing sample containers with an automatically readable identification for an analysis device, in which the sample container may be heated to an operating temperature for analysis. It is the object of the invention to improve the identification of sample containers in a manner that the sample contained in the sample container is not contaminated by the constituents of the identification agent during analysis. The object of the invention is solved in that the identification is applied at an elevated temperature above the operating temperature. By the method according to the invention, volatile constituents of the identification agent are advantageous evaporated so that when using the sample container during operating temperature of the analysis device, the sample to be analyzed is no longer contaminated by the exhaling constituents of the identification agent.

A method of providing sample containers with an automatically readable identification for an analysis device, in which the sample container may be heated to an operating temperature. It is the object of the invention to improve the identification of sample containers in a manner that the sample contained in the sample container is not contaminated by the constituents of the identification agent during analysis. The object of the invention is solved in that during the manufacturing process of the sample container, the identification is applied during the final cooling phase of the ready sample container in a temperature interval between a maximum temperature during the sample container manufacture and the operating temperature. By the method according to the invention, volatile constituents of the identification agent re advantageous evaporated during the manufacturing process, so that when using the sample container during operating temperature of the analysis device, the sample to be analyzed is no longer contaminated by the exhaling constituents of the identification agent.
