The aim of the invention is to reduce the collection of moisture on a welding wire (2, 2, 2) arranged in a welding wire cartridge (1, 1a, 1b) or to remove moisture present on the welding wire in a simple and reliable manner. This is achieved in that a flow (D1) of purge air supplied to the welding wire cartridge (1, 1a, 1b) is adjusted by a flow regulator (14), the purge air is supplied to the flow regulator (14) with a first pressure (p) and is discharged at a purge air outlet (24) of the welding wire cartridge (1, 1a, 1b) with a third pressure (pat), and a second pressure (p1) which is lower than the first pressure (p) is produced at a purge air inlet (15) of the welding wire cartridge (1, 1a, 1b) from the adjusted flow (D1), the third pressure (pat), and a flow resistance between the purge air inlet (15) and the purge air outlet (24), wherein the relative moisture (r F1) of the purge air is reduced by the relief of pressure from the first pressure (p) to the second pressure (p1).

Five DSOs (CEZ distribuce, ERDF, EON, Enexis, Avacon) associated with power system manufacturers, electricity retailers and power system experts, propose a set of six demonstrations for 12 to 24 months. Within three years, they aim at validating the enabling role of DSOs in calling for flexibility sources according to local, time-varying merit orders. Demonstrations are designed to run 18 separate use cases involving one or several of the levers increasing the local energy system flexibility: energy storage technologies (electricity, heat, cold), demand response schemes with two coupling of networks (electricity and gas, electricity and heat/cold), the integration of grid users owning electric vehicles, and the further automation of grid operations including contributions of micro-grids. The use cases are clustered into three groups. Three use cases in Sweden and the Czech Republic address the enhancement of the distribution network flexibility itself. Five use cases in France, Germany and Sweden demonstrate the role of IT solutions to increase drastically the speed of automation of the distribution networks, which can then make the best use of either local single or aggregated flexibilities. Ten use cases in Czech Republic, France, The Netherlands and Sweden combine an increased network automation and an increased level of aggregation to validate the plausibility of local flexibility markets where both distributed generation and controllable loads can be valued. Replicability of the results is studied by the DSOs and industry with an in-depth analysis of the interchangeability and interoperability of the tested critical technology components. Dissemination targeting the European DSOs and all the stakeholders of the electricity value chain will be addressed by deployment roadmaps for the most promising use cases, thus nourishing the preparation of the practical implementation of the future electricity market design, the draft of which is expected by end of 2016.

The INLINE project aims at the solution of key challenges to enable the implementation of a scalable manufacturing process for fuel cell systems. Current manufacturing processes rely on manual work that has substantial limits in terms of cycle times, costs and scalability. Developments will start with the re-design and optimization of two key components: the media supply unit and the tank valve regulator. Both are components that are currently difficult to manufacture and are perceived as bottlenecks in the production process. Based on these new designs, an integrated production line will be planned using simulation tools. These tools will enable the evaluation of different layouts, part flow strategies and for different production scenarios. In terms of manufacturing tools, the end of line test will be improved to reduce cycle times by a factor of 3 and assistance systems for assembly stations will be developed that will enable scalability by reducing the need for training of workers. The overall target is to reduce the cycle time for production of a whole fuel cell system from 15 hours to less than 2.5 hours. Data gathering and analysis methods will be developed to enable the tracking of parts through the production line and - through a correlation of process and quality data - the continuous improvement of the production process. Demonstration of the end of line test and the assistance system will be done in hardware. The whole production line will be evaluated using a simulation tool that has been verified on the current production process. A set of engineering samples of the re-designed tank valve regulator and the media supply unit will be produced and used for tests of the integrated fuel cells and for assessment of the whole production process.A potential of 250 new jobs in manufacturing of fuel cells and for production of the key components will be generated by the project.

A device and a method for contacting a welding wire in a welding torch includes at least two contact shells having a contact area for contacting the welding wire. In order to make the contact of the welding wire as constant and permanent as possible during the lifetime of a contacting device, the contact shells have a holding section and are arranged inside a sleeve to define a rotational axis, the sleeve being fastened to a nozzle pipe having an integrated pressure mechanism. The pressure mechanism is adapted to exert pressure on the contact shells. The sleeve includes a holding device for exerting a counter-force onto the contact shells. The welding wire is contacted in the contact area of the contact shells with a contact force.
