The solid oxide fuel cells produced by VPS-Technology have been investigated in this work. Using the thin film concept, various anode substrates were tested. At first, the relevant transport processes were experimentally studied under operating conditions if possible. These processes are the flow in gas channels, and the gas permeation through and the diffusion in the functional layers, respectively. A mathematical 3-D model has been developed to simulate the flow field distribution, and the numerical calculations have been implemented using the CFD program Star CD. The 3-dimensional flow distribution has been studied using laminar and turbulence models. Furthermore, the experimentally determined parameters were used into the porous model, and the influence of the porous structure on the distribution of flow investigated.
