Abstract
The main objective of this article is to compare two cross-sectional shape type: trapezoidal and rectangular serpentine flow field used in PEMFCs cells, employing computational fluid dynamics (CFD) technique. The effects of different parameters on the behavior on the fuel cell that were investigated include the water concentration, pressure and velocity distribution and membrane current density. In general, the trapezoidal format, besides contributing to the accumulation of water in the channels of the cathode, also presents the tendency to an irregular pressure drop. The fuel cell with rectangular channel was equivalent to the trapezoidal cell in polarization curves. However, the current generation in the rectangular design was slightly higher. The contribution of this work is in the dissemination of the knowledge of the use of computer simulation to solve problems in PEM fuel cells.
