Research Unit I: Multiphysical simulation of degradation processes

  • Prof. Jan Lohbreier’s research group uses computer-aided simulations to model natural phenomena. To this end, fundamental physical equations are solved numerically, e.g., using the finite-element method.
  • In the simulation of the PEMFC it is particularly important to be able to consider phenomena in a coupled manner, as they strongly influence each other. For example, a model is being worked on that can simultaneously depict the gas flow, heat transfer, and the electrochemistry within the fuel cell.
  • We can use these models to support the other subprojects in the laboratory, for example, by replacing experiments or deriving test procedures from the simulations. Also, experiments cannot adequately investigate all influencing variables, as it is not possible to look inside the PEMFC while it is in operation, for example. Specifically, our subproject supports Maik Eichelbaum (RU A) and Frank Opferkuch (RU D) gain such views inside the fuel cells.
  • To increase the reliability of the numeric simulations, their prognoses will be validated using measurement data in close collaboration with the colleagues conducting the experimental work.
  • Stochastic simulation methods will also be used to provide predictions about nanomaterials. This will be primarily investigated in collaboration with Uta Helbig’s group (RU C) that is investigating new materials for use in PEM FCs.
