Numerical Simulation in fuel cell development

Within the research and development at ZBT concerning fuel cells many tasks are analyzed and designed by numerical simulations. At ZBT numerical simulations are performed in the field of fluid mechanics, thermodynamics, electro-chemistry, chemical process engineering, and mechanics / stress analysis with the appropriate simulation tools. As a non-profit limited company for industry-related research and development ZBT supports industry by means of numerical simulations. Additionally, within the process chain of numerical simulations (modelling, parametrization, calculation, analysis and presentation) ZBT especially focuses on modelling, since the development of fuel cells requires a fundamental understanding of electro-chemical, fluid mechanical and structural mechanical phenomena. Numerical simulations are supported by experimental analysis, e.g. in the field of fluid mechanics by laser-optical flow measurements.
