Systems Research

Experimenteller Aufbau - NT-Verschaltung

In the field of SOFC systems research three areas are treated crosslinked. These include modeling, technique, and experiment. All priorities aim to solve the challenges of the SOFC 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.

System

In the field of technique, 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 SOFC 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 SOFC systems. This includes, for example, the developed integrated module that combines all system components and thus saves weight, space and costs.
