| Abstract: | Mass transfer in the cathode of a Proton Exchange Membrane Fuel Cell (PEMFC) using electrode structures called Interdigitated Gas Distributors was numerically simulated using a commercial Computational Fluid Dynamics(CFD)software, CFX4.3. The computation gives reasonable pressure, velocity field and composition distributions of the oxygen and steam. Besides, it is also discussed that the effect of the electrode structure (porosity) and the operation condition (pressure difference of the inlet and outlet). |
