Numerical Analysis of Mass Transport and Water Management
Краткое описание
A full three-dimensional and single phase Computational Fluid Dynamics (CFD) model of a proton exchange membrane fuel cell (PEMFC) with the both gas distribution flow channels and the Membrane Electrode Assembly (MEA), has been developed. A single set of conservation equations which are valid for the flow channels, gas diffusion electrodes, catalyst layers and the membrane region are developed and numerically solved using a finite volume based technique. In this research, some parameters such as oxygen consumption, water production, temperature distribution at various cell voltages were studied. On the other hand, the operating pressure which its effect is studied in this paper, is one of the most important parameters that affect the cell performance and transport phenomena. In addition, the effect of Gas Diffusion Layers (GDLs) geometrical configuration on cell performance showed that the observed model, with prominent GDLs, enhances the cell performance compared with the conventional model. The deflected MEA effect on cell performance has been investigated and the δ = 0.4 is chosen as the better model than the others. Finally, the numerical results are compared with the available experimental data which revealed good agreement.
