The Simulation of a PEMFC with an Interdigitated Flow Field Design
نویسنده
چکیده
This paper presents the simulations for a two-dimensional PEMFC with an interdigitated flow channel design using FEMLAB. The multi-species flow of O2, H2, H2O and inert N2 is examined over the entire fuel cell working range. The transportations of these gases in the porous anode/cathode are predicted using the Maxwell-Stefan transport equations and the Fick’s law; the flow field is predicted using the Darcy’s law; and the electrical field is simulated using a conductive media model. The standard current-voltage performance curve, the species concentration of O2, H2, H2O and inert N2, mass fluxes, electrical current and potential distributions have been obtained.
