AB - In this study, a simple two-dimensional, unsteady Proton Exchange Membrane Fuel Cell (PEMFC) model is developed and validated by experimental results. The numerical model
considers fluid flow, mass transport and electrochemical reactions in the PEMFC cathode. The
vorticity-stream function method and Alternating Direction Implicit (ADI) scheme are employed
to solve the coupled fluid flow equations effciently. The I-V characteristics obtained from the
numerical model are in good agreement with the experimental results. The simulation results show
that the gas flow velocity, concentration of oxygen and porosity of gas diffusion layer significantly
infl
uence the cell performance. Moreover, it could be inferred that, despite the real flow is three-
dimensional, a two-dimensional numerical model is time-effcient to predict the location of liquid
water formation and the fuel cell performance satisfactorily in some circumstances.
