The bipolar plate includes an inlet, an outlet, and a flow field having a pattern defining a plurality of microchannels configured to provide fluid communication between the inlet and the outlet. The pattern includes a plurality of channels with discrete areas of discontinuity to direct fluid from the inlet to the outlet. The pattern is designed using an inverse permeability field and is based on a reaction-diffusion algorithm to model channel spacing, thereby providing a variable pitch microchannel pattern. In various aspects, Gray-Scott reaction-diffusion equations may be used to obtain an anisotropic microchannel layout. Methods may include optimizing a porous media model domain for one of: a minimum flow resistance across the domain, a uniform velocity across a direction of the domain, and a minimum velocity across a direction of the domain."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Fuel cell bipolar plates with flow uniformity","description":"A bipolar plate with an enhanced fluid flow field design is provided for improved flow uniformity.
