Abstract:	A multidimensional dynamic model of a proton exchange membrane (PEM) fuel cell is presented. The model comprises of the polymer membrane, the catalyst layers, the gas diffusion layers, the bipolar plates and the gas channels. The modelled processes include the two-phase flow, the chemical reactions, the heat balance, the charge balance and the transport of species and momentum, which are all treated dynamically. This results in a coupled system of nonlinear partial differential equations for the physical and electrochemical processes. These are solved numerically by the finite element and the finite volume methods. The approach is an extension of where the energy balance in all layers is additionally accounted for. Moreover, a detailed two-phase membrane model based on results in a more realistic membrane water transport process that accounts for Schroeders paradox and the associated structural change of the membrane. Two dimensional simulation results are presented that relate the current-voltage-characteristics to the state of the fuel cell components, e.g. the flooding level of the gas diffusion layer and the structure of the membrane. As an example, the response of the fuel cell to increasing current is studied. Good agreement with experimental observations is obtained. A stack model is currently being developed that is based on the single cell modeling approach.
