This study presents a thorough and affordable reduced-order computational multiphysics modeling framework to design advanced flow fields in Proton Exchange Membrane Fuel Cells (PEMFCs) using topology optimization. No assumption is made about the layout of the channels, which freely evolves along the optimization process, resulting in non-trivial optimized geometries. The optimization problem is formulated to maximize both the power generation and homogeneity of current density distribution, in the spirit of reduced costs and increased durability. The topology-optimized designs yield significant power generation enhancements, an improved reactant distribution and a reduced pressure drop as compared to conventional flow fields.
