A method for modeling of mass and / or heat transfer processes in a device, as well as apparatus for carrying out the method

The development of high temperature fuel cells (SOFC) up to the kW range makes it necessary for the planning developments, in particular the Upskalen, proven Konzpte by appropriate modeling support. However, the software used so far comes across because of the increasing number of single cells quickly both to capacity limits and the limits of a realistic calculation time. More particularly, the invention relates to a method for modeling of high temperature fuel cells in the kW range. Unlike the prior art, in which the resolution of the computational grid of the models is linked to the relatively small detail dimensions of the individual cells, the new concept is independent of the detailed dimensions of the individual cells. Thereby, advantageously achieves a reduction in the computational grid and an order of magnitude advantageously be correspondingly reduced as a result of the computation time. The inventive method can, however, advantageously transmitted to all devices having at least two fluid chambers, and wherein a complex geometry and / or very small dimensions of the fluid chambers are given.
