Fraunhofer Institute for Ceramic Technologies and Systems IKTSIn this field, Fraunhofer IKTS is focusing on the development of materials with improved corrosion stability in molten carbonates and chlorides. In case of ceramic materials, we deal with the synthesis of powder materials, their sintering, preparation and characterization of defined components. The following applications are addressed:
Molten-salt electrolysis in chlorides
- Investigation of CaRuO3 as an inert-anode candidate material, potential for energy-efficient extraction of metals and oxygen from minerals
Molten-carbonate fuel cells (MCFC)
- Stabilizing defined phases of LiAlO2 at high temperatures (600-700°C) in molten alkali carbonates under different gas ambience
- Preparing corrosion protection and anti-adhesion layers for molten carbonates
In-situ electrochemical characterization
- MCFC materials, CO2 gas sensors, proton conductors
Specifications of test equipment
Box furnaces
- Air, N2 (up to 1400°C), reducing gas mixtures (up to 1100°C)
MCFC half-cell test rigs, adaptable for testing other components
