(A) Schematic of the electrochemical flow cell. The porosity of the 3D printed lattice cathode is optimized to reduce the power losses from the pressure and potential drops. Porosity control is achieved through tuning the thickness of the constituent rods within a lattice. (B) Schematic of an electrode with thin rods. Arrows indicate high permeability to liquid flow but low electronic conductivity and reaction surface area. (C) Schematic of an electrode with thick rods, which has a low permeability to fluid flow but offers higher electronic conductivity and reaction surface area. (D) Schematic of an electrode with a heterogeneous distribution of rod sizes which can achieve an optimal balance fluid permeability, charge conductivity, and reaction surface area. (E) Schematic of the transport processes taking place within an individual unit cell of a 3D printed electrode. These processes are simulated using continuum scale modeling. (F) Image of a 3D printed electrode with a gradient of rod thicknesses.
