Modelling a fuel cell electrode with inhomogenious parameter distribution.

  • Our electrode model takes into account the carbon with catalyst, Nafion distribution and pores, which are (partly) covered with liquid water. The simulation enables e.g. the investigation of current production due to proton / current conductivity within the electrode
  • Extracting catalyst layer properties by an analytical catalyst layer model in order to analyze degradation e.g. by accellerated stress tests
  • Water transport in porous media. We apply an innovative approach by coupling of a continuum and a discrete model
  • Modelling of electro-chemical impedance spectra with electrical networks
  • System modelling to optimize system efficiency by studying different operation strategies
