Zusammenfassung
For the design and analysis of fuel cell systems there is an increasing need for adequate modelling and simulation tools. In the present contribution, a modular modelling strategy is proposed which is based on the network theory for chemical engineering processes. According to this network theory, a fuel cell system is decomposed into elementary units on several hierarchical levels (process unit level, phase level, storage level). After decomposition, the model formulation starts on the storage level: electrochemical source terms were combined with the diffusive and convective transport phenomena and state equations, forming an elementary unit of the phase level. On the phase level several thermodynamic phases (e.g. fluid compartments, electrode backings, catalyst layers and the membrane electrolyte) are aggregated to a single fuel cell unit. Finally on the top level, the process unit level, single cells or fuel cell stacks are combined with other process units to form a complete process model. This modelling procedure is demonstrated with a simple proton exchange membrane fuel cell system operated with hydrogen and oxygen. © 2005 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
