High Tech Tubings

Widespread knowledge in the field of extrusion of various polymers will function as a basis to develop, beside basic analysis of producibility of a tubular membrane with diameters of       < 5 mm, an extrusion process for serial production of tubular membrane and membrane-electrode-assemblies in this subproject.

Out of initially theoretical considerations regarding the production process (of tubular membrane) there will be a progress of constructional designing of machinery and tooling, followed by defining manufacturing parameters and realising an experimental production with suitable materials. Usage of promising, application fitted and more sophisticated polymeric materials from Fumatech shall be used for extrusion tests by Uniwell, to first form an optimized tubular membrane, later a prototype of a membrane-electrode-assembly.

In principle this subproject is based on optimisation of processing properties of Fumatech materials, to the end of a trouble-free, process-safe extrusion of a tubular membrane with defined low wall-thickness right up to 50 μm.

Process-safe production of tubular membrane initiates the next step in development – production techniques for a tubular membrane-electrode-assembly. Depending on that an extrusion line for production of tubular MEA will be build up for realizing Inline-assembly of membrane and electrode. On the one hand the subproject includes principles of trial, but also the aspect of a broad rollout of tubular systems with high economical efficiency.

On this basis later there will be the chance to demonstrate a competitive price segment.
