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.}, issn = {}, doi = {https://doi.org/}, url = {http://global-sci.org/intro/article_detail/ijnamb/329.html} }
