| Zusammenfassung: | Macro-homogenous models enable the study of the complex interplay between operating conditions, materials response and cell performance, which is needed for the optimisation of the cell performances. However, input parameters to the macro-homogenous models are needed to account for the micro-scale properties of the single components and interfaces. For this purpose the water filled and open pore domains of gas diffusion layers (GDL) are determined depending on the boundary (and operating) conditions using the geometric input of the fiber/pore morphologies provided by tomography. The ultimate aim is to calculate the effective transport properties for different degrees of saturation, based on water distributions that are obtained with pore-scale modeling and from tomography. Considering the liquid water as statistical ensemble, a Monte Carlo-based approach based on the energetic balance between solid, liquid and gaseous phases in the porous medium, has been used to determine water distribution. PSMC (Pore Scale Monte Carlo) code we developed, is shown to be able to simulate the equilibrium distribution of the water (EWD) in the porous structure, minimizing the surface free energy of the water-solid-air system. Such an information will be later used to calculate the effective transport properties (e.g. permeability, conductivity) needed for a macroscopic simulation of the full PEM fuel cell. |
