    Our environment is under increasing pressure from chemical pollutants contaminating soil, water, and air. Particularly concerning are persistent substances such as per- and polyfluoroalkyl substances (PFAS) and pharmaceutical residues. These belong to a group of over 4,700 compounds whose effects on human health and ecosystems remain largely unknown. Despite advanced wastewater treatment technologies, any of these pollutants still enter the environment, threatening fragile ecosystems – even in remote regions like the Arctic. This is where the R&D project DeDrug-Bio comes in. By leveraging biohybrid filtration systems, harmful substances can be removed efficiently and sustainably – an innovative approach that seamlessly integrates nature and technology.

  • COMMON CHALLENGES FOR ENERGY SUPPLIERS, COMMUNES AND THE HOUSING INDUSTRY | The sustainability goals at federal and state level in Germany require a climate-friendly heat supply. The goal of a climate-neutral building stock by 2045 can only be achieved through an innovative and sustainable heat supply. Therefore, energy suppliers and communes as well as the housing industry must face common challenges and work together in order to master them. Fraunhofer IFAM provides support with strategic planning of the heat supply and takes into account the various possible supply options and their economic efficiency.

    PROJECT “BioRUHM”: REACTIVE URETHANE-FREE HOTMELT ADHESIVE | Reactive hot-melt adhesives (RHM) based on isocyanate are increasingly being used due to their exceptional properties, from packaging to automotive construction and technical textiles. However, the composition of these urethane-based adhesives also involves risks, e.g. the release of hazardous isocyanate. In the “BioRUHM” project, Fraunhofer IFAM is working with project partners to develop a urethane-free concept.

  • Bipolar plates from the ZSW are fixed in the printing nest using negative pressure. The structure of the printing nest and screen allow simultaneous coating on the anode (left) and cathode side (right) for each printing process. For printing on the reverse side, the bipolar plates are returned to the screen printing process after curing.

    METHODS FOR APPLYING SEALANT TO BIPOLAR PLATES USING SCREEN PRINTING | Fraunhofer IFAM is your competent partner for innovative research services in the field of fuel cell production. In addition to industrial projects in this context, we are active in public research projects - including the National Action Plan for Fuel Cell Production (H2GO). The National Action Plan maps the key sensitivities of the value chain in the production, stacking and recycling of substantial fuel cell components. Fraunhofer IFAM is, among other things, researching the use of the screen printing process for applying sealants to bipolar plates, which has several other advantages in addition to reducing production costs.

  • SALT SPRAY, CROSS-CUT AND G1C TESTING ACCORDING TO NADCAP | Since March 2020, parts of the laboratories at the Bremen site have been recognized under the Nadcap conformity system relevant to the aviation industry. The successfully obtained Nadcap "accreditation" as an independent testing laboratory in the field of chemical processing applies, among other things, to the cross-cut test according to DIN EN ISO 2409 and the salt spray test according to DIN EN ISO 9227, which are important for coatings. In the field of Non-Metallic Materials Testing (NMMT) recognition has been valid since June 2021 for the testing of composite materials (CFRP) according to AITM 1-0053 (G1c procedure).

    DEVELOPMENT OF ROTORS FOR EFFICIENT INDUCTION MACHINES (IM) | Fraunhofer IFAM is developing solutions for more economical and efficient Induction machine (IM). IMs are still widely used in electrical drive applications, particularly in the field of industrial drives. They are robust and cost-effective and can start up directly from the line without a frequency converter if required. Even in vehicle technology, IMs are certainly far from being replaced . New manufacturing approaches continue to offer potential for increasing efficiency, reducing costs and improving production quality.

    The approach of the multidisciplinary, automated design process chain enables faster and application-oriented development of innovative e-machines

    MULTIDISCIPLINARY DESIGN AUTOMATION AS A SOLUTION TO CURRENT CHALLENGES | As electrification progresses and the use of inverter-fed electric motors increases, manufacturers and developers face new challenges. Ever-shorter development cycles, coupled with constantly rising demands for efficiency or torque density, require innovative approaches in the multidomain development of electric machines. A promising solution lies in the creation of integrated simulation-driven design workflows that enable the automated generation and evaluation of various designs. At Fraunhofer IFAM, specific methods and demand-driven design workflows are being developed to quickly create designs for electric machines and evaluate them in light of manufacturing and materials science innovations.

    HOCHDREHZAHLANTRIEB ZUR LEISTUNGSSTEIGERUNG EINES ELEKTRISCHEN LUFTVERDICHTERS EINER BRENNSTOFFZELLE | Brennstoffzellen spielen für die Dekarbonisierung eine tragende Rolle. Die Optimierung der Leistungsfähigkeit und Zuverlässigkeit von Brennstoffzellensystemen bei extremen Betriebsbedingungen ist daher aktuell stark gefragt. Besonders die hohen Drehzahlen stellen eine Herausforderung dar, da sie zu einer erhöhten Wärmeerzeugung führen und so die Leistung des elektrischen Luftverdichters und damit der Brennstoffzelle negativ beeinträchtigen können. Um dem entgegenzuwirken, wurde am Fraunhofer IFAM ein elektrischer Luftverdichter mit Flüssigkeitsinnenkühlung und erhöhter Fliehkraftfestigkeit entwickelt.
