Abstract: One or more methods of designing an FC bipolar plate that enhance the operational performance of FC. A first image analysis is conducted of image data of a fluid flow field structure having one or more dehomogenized microstructures to identify channels having a fluid flow blockage at a channel wall dead-end. The channel wall dead-end of each identified channel is selectively removed in a manner that fluidically connects each identified channel to an adjacent channel. Then, a second image analysis of the image data is conducted in response to selectively removing the channel wall dead-ends to measure a length of each channel wall. Channels walls having a length greater than a threshold channel wall length value are selectively cut, thereby providing reduced fluid flow resistance throughout the FC.
