Green hydrogen is one of the energy sources of the future. In order to produce it in large quantities, store it and convert it back into electrical energy, however, the industry needs efficient and scalable production processes and systems for the required electrolysers and fuel cells. Scientists at the Fraunhofer Institute for Production Technology IPT in Aachen are focusing on both conventional discrete and continuous production processes using roll-to-roll systems (R2R). At the Hannover Messe from April 22 to 26, 2024, Fraunhofer IPT will be exhibiting parts of its modular system technology "Scalab," the bipolar plates and membrane electrode assemblies (MEA) produced with it, as well as pressure tanks for storing hydrogen.
