COUNTERING DIFFUSION AND EMBRITTLEMENT IN THE STORAGE AND TRANSPORT OF HYDROGEN | Green hydrogen will play a decisive role in a successful energy transition. The development of new hydrogen technologies requires techniques and processes that enable the safe production, storage, distribution and use of hydrogen. Central material science challenges are the diffusion of hydrogen and the associated embrittlement of used material. The "Plasma Technology and Surfaces" department at Fraunhofer IFAM is researching how surfaces can be protected against this diffusion and embrittlement by treatment with plasmas or lasers. The focus is on internal coatings for tanks and pipes, but possible applications for electrolysers, bipolar plates, and fuel cells are also being investigated.

The aviation industry is undergoing change: Innovation cycles are becoming shorter, and production and manufacturing requirements regarding cost-effectiveness, emissions, and environmental sustainability are increasing. To meet these challenges, the aircraft components of the future must be more cost-effective, flexible, and environmentally friendly. The Fraunhofer IFAM supports this transformation in the "MORPHO" project. The goal: a quieter, more efficient, sustainable, and economically viable aviation industry of tomorrow. Using an aircraft turbine blade as an example, our researchers have demonstrated the potential of integrated sensors.

We strengthen your team’s technical understanding and build a solid foundation for reliable, low-defect casting processes.

A NEW GENERATION OF GAP FILLERS FOR HEAT DISSIPATION FROM BATTERIES IN E-CARS | Heat dissipation from batteries is essential to protect them from overheating. This increasingly affects the batteries used in e-cars and other electric vehicles. Only if the batteries are protected from overheating, strong drive performance and long vehicle life can be ensured. This is enabled with gap fillers.

PRINTED CONDUCTIVE STRUCTURES MADE OF SPECIAL ALLOY | Fraunhofer IFAM has the expertise and equipment to produce printable metal and alloy inks for special applications. These inks made from special alloys for digital printing techniques offer opportunities for cost-efficient new products in the field of printed electronics and sensor technology in a wide range of industries.

STRESSES IN THE BOND LINE AFTER ADHESIVE CURING - CAUSE AND EFFECT | The most common causes of stresses in bond lines during adhesive curing are the volume reduction of the adhesive due to curing and different thermal expansions of the adhesive and the joined parts or of two different joined parts. When designing adhesive bonds, the question of volume reduction, also known as curing shrinkage, is crucial. It is important to determine the material value and understand how much volume reduction actually causes stress.

THERMALLY CONDUCTIVE HEAT SINK MATERIAL FOR 3D PRINTING AND FUNCTION INTEGRATION OF ELECTRONICS | The integration of electronics or LEDs in additively manufactured plastic components involves heat dissipation during operation. Using 3D printing (Fused Filament Fabrication, FFF), thermally conductive plastic composites can be used as heat sinks. The material and process development for applications in the automotive and lighting sectors was part of the »Hyb-Man – Hybrid 3D Manufacturing of Smart Systems« project.

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.

RECYCLING OF FUEL CELLS: ADHESIVE STRATEGIES FOR ASSEMBLY AND DISASSEMBLY | Fuel cells are an elementary component for the use of climate-friendly hydrogen in the transport sector. Fraunhofer IFAM is part of the technology alliance Stack2P in the national project H2Go in the national action plan for fuel cell production funded by the ministry of transport. A central goal is the development of recycling-friendly manufacturing technologies for fuel cells based on the principle of “Design for Recycling” and the implementation in an assembly and disassembly platform for the subsequent transfer of the components into scalable reuse, repair and recycling concepts. The goals are to increase product quality and reduce the product development cycle and development costs as well as reduce production errors.
