  • A Scalable PEM fuel cell modelling approach to support FCEV component and system development [Elektronski vir]
    Tatschl, Reinhard ...
    The need for a further reduction of costs by simultaneously achieving increased power density, performance and long-term stability of proton exchange membrane fuel cells (PEMFC) requires tools and ... methods for advanced component / system layout and optimization to address the challenges of today's technology. A scalable simulation methodology is presented, consisting of a 3D-CFD based multi-physics simulation method and an innovative hybrid 1D+2D numerical-analytical approach. The results of the 3D-CFD method provide a detailed insight into the governing transport and reaction processes in the PEMFC, and hence support the flow field design, MEA selection, cooling concept layout, degradation analysis, etc. on cell and stack level. The hybrid 1D+2D approach is aiming at supporting the PEMFC system development regarding layout and optimization of the balance-of-plant (BoP), the related components dimensioning, HiL based system calibration purposes, etc. The paper first describes the underlying theoretical background and modelling concepts adopted in the 3D-CFD and hybrid 1D+2D approaches, presents selected cases for validation of the two methods by comparing simulation results with corresponding experimental data and finally provides simulation results for typical industrial PEMFC applications.
