Materials for Printed Systems

Group

We have special expertise in the development of powders and powder suspensions (pastes, slurries and inks) for various coating technologies (screen printing, dispensing, inkjet and aerosol printing, tape casting, vacuum slurry casting etc.) as well as scientific and engineering knowledge in the field of physical material properties, chemical interactions and high-temperature electrochemistry. For realizing functional layers composite materials have often to be used. The focus is on the development of materials as well as paste and slurry technology, especially for the best dispersion of different powders and the structuring of interfaces between electron and ion conductors. Based on our experiences with metal oxides (perovskite), spinell, fluorite, noble metals and carbon-based materials we work on solutions for different tasks. With the help of the developed materials more complex components such as MEAs, SOFC stacks, sensors as well as battery and capacitor electrodes are built up and qualified for system integration.
