Simulation and study of proposed modifications over straight-parallel flow field design

Diverse CAD (Computer aided-Design) 3D bipolar plates model are presented. By using the OpenFOAM software, an open source CFD (Computational Fluid Dynamic), hydrogen flow simulations were carried out, obtaining velocities and pressure maps for each model. bjective resides on predict the flow behavior in response to the modifications proposed on the bipolar plate geometry, such as width, depth and shape of the distributing channels (collectors) as over the main channels. Channelers fins are also besought with the purpose of direct the flow towards different zones, in order to homogenize the flow distribution.
