The SOC department’s expertise lies in the development, characterization and optimization of high temperature electrolysis and fuel cell stacks and systems. Thereby, stacks as well as systems and system components are conceived, designed, constructed, modeled, constructed, tested and electrochemically analyzed. Thermo-mechanical and procedural models developed in parallel to the experimental investigations serve to optimize the components and systems, as well as to evaluate different concepts.


Electrochemical measurement techniques

Electrochemical measurement techniques
• Electrochemical characterization of stacks in both the fuel cell and the electrolysis operation, inter alia by means of electrochemical impedance spectroscopy

• Performance and stability measurements under various test conditions

• Analysis of the degradation processes, as well as the thermo-mechanical effects

• Further development of the stack design and validation in the development of computational models.


Modelling and Simulation

Modelling and Simulation
• Supporting stack and system development by simulations as cross-cutting task

• Analysis of the performance of system components and of SOFC/SOE Stacks from various viewpoints using CFD (Computational Fluid Dynamics) and FEM (Finite Element Method) simulation methods

• Providing decisive impetus for the improvement of stacks and systems


Systems Developement

Systems Research
• Design and lay-out of systems architecture

• Lay-out, design, and test of the peripheral system components, essential for system operation

• Development of dynamic component and system models

• Construction of demonstration systems up to 20 kW electric power, which also allow the use of hydrogen, for example for reconversion

• Optimization of system control and management

• Development and characterization stacks and systems for high-temperature electrolysis (SOE) and the combination of both (rSOC), based on the development of SOFC

• Investigation concerning their suitability for energy storage.
