description Electrochemical reactors with electrodes that have variable porosity across the electrode and associated methods are described. The electrodes are designed and micro-architected to have variable porosity and 3D flow. One example method of selecting porosities in an electrochemical reactor includes dividing an electrode of the electrochemical reactor into a plurality of unit cells and determining a plurality of cell-specific porosities for the plurality of unit cells as a function of a location for each of the plurality of unit cells. The cell-specific porosities are configured based on a rod diameter of each unit cell's internal structure relative to each unit cell's cell length, and each location in the electrode provides a selected fluid flow property and a selected conductive property to meet one or more performance metrics.
