Abstract
A bipolar plate for a fuel cell, a fuel cell, and a method of designing a bipolar plate for a fuel cell having a hybrid flow field structure that includes a plurality of parallel feed flow channels fluidically connected to an inlet bipolar plate region, a plurality of parallel exit flow channels fluidically connected to an outlet bipolar plate region, and an interwoven pattern formed by a plurality of simplified periodic array flow field structure generated based on flow patterns generated by homogenized anisotropic porous media optimization. The flow field structure enhances fuel cell performance by facilitating lower pressure drop via minimized fluid flow resistance, and removal of accumulated water in the oxygen channel and the gas diffusion layer (GDL) under the ribs of the bipolar plate.
