System Research
In the field of SOC systems research three areas are treated crosslinked. These include modeling, technique, and experiment. All priorities aim to solve the challenges of the SOC systems and establish this technology as a future technology.
In the field of modeling, besides the classical CFD (Computational Fluid Dynamics) and FEM (Finite Element Method) simulation methods also own model libraries in Matlab Simulink are used for component sizing and system analysis. The expertise thus built up in the field of dynamic system simulation has already led to shorter component design times, targeted analyzes of existing challenges, for example in the field of system operation strategies and a reduced number of expensive experiments. In the future, this supports the research of thermal cell and stack loads, shorter heating times with simultaneously reduced thermal stresses, reduced load change times and more efficient operating strategies.
In the field of system technology, the required system components are designed and constructed. These include high temperature heat exchanger, reformer, catalytic and thermal off-gas burner and high temperature electrical heating elements. In addition, current research challenges are solved by exploring innovative components, such as a safety gas generator for the integrated supply of safety gas within an SOC system. By considering the complete system (ranging from electronics over components to the total system) innovative system approaches are being studied, enabling the launch of production-ready SOC systems. This includes, for example, the developed integrated module that combines all system components and thus saves weight, space and costs.
Modellierung and Simulation
As cross-sectional task stack and system development is supported by simulations. The performance of system components and of SOFC/SOE Stacks is analyzed from various viewpoints using stationary and transient one-dimensional energy balance simulations as well as three-dimensional CFD (Computational Fluid Dynamics) and FEM (Finite Element Method) simulation methods. These studies provide a decisive impetus for the improvement of stacks and systems.
