Bio-Inspired Inverse Design Enables Innovation in Hydrogen Fuel Cell Flow Field Plates

Research, In the News


Members of the  Toyota Research Institute of North America’s Electronics Research Department (ERD) published a paper titled “Inverse design of microreactor flow fields through anisotropic porous media optimization and dehomogenization” to Chemical Engineering Journal.

This paper highlights an inverse design and dehomogenization framework for discovering innovative microreactor flow field designs. The method exploits bio-inspired Turing pattern dehomogenization to generate microchannels. The optimized flow fields exhibit similar geometric patterns to those observed in naturally occurring systems (e.g., lungs, leaves, and blood vessels). The optimized flow fields further outperform conventional parallel and serpentine benchmark designs. ERD is now looking to apply the method to design future generation Toyota Fuel Cell stacks.
