Computational analysis of the machining and design parameters in the flow conditions of the electrodes in the PEM Cells

摘要

This paper shows a comparative analysis of the effect of the machining angle through the simulations of non-isothermal multidimensional fields flow though electrodes for proton exchange membrane (PEM) cell. Different designs of channel (coil, parallel and pin-type), positions of the inlet feed gas, just as the effect of curvature machined into different sections of the channels according to some relevant aspects as the relation between the channel dimensions were used. The flow analysis is performed to determine the following: pressure load losses, gas distribution, gas velocity in the electrode and the residence time. The research was developed using computer-aided design (CAD) and computational fluid dynamics (CFD) software, and the results were compared with experimental data in the literature.
