The present disclosure relates to an engineered, additively manufactured, microfluidic cellular structure formed from a plurality of cells, wherein the cells are each formed from a plurality of interconnected elements. The cells have voids and each cell is open at upper ends thereof. The cells each communicate at a point below its upper end with a common channel. The cells are each configured to accept a fluid and operate to channel the fluid into the common channel and to hold the fluid received therein for later selective withdrawal from the structure.

Systems and methods for reaction and transport engineering via cellular fluidics

Disclosed are electrochemical reactors with electrodes that have variable porosity across the electrode. The electrodes are designed and micro-architected to have variable porosity and 3D flow. In one aspect, an electrochemical cell apparatus is disclosed. The apparatus includes an electrochemical vessel and an electrochemical fluid contained in the electrochemical vessel. The apparatus further includes a porous electrode submerged in the electrochemical fluid in the electrochemical vessel, the porous electrode having different porosities in different areas of the porous electrode. The different porosities inhibit electrochemical fluid flow and increase electrical conductivity in first areas of the porous electrode with decreased porosity compared to second areas, and enable increased electrochemical fluid flow and decrease electrical conductivity in the second areas of the porous electrode with increased porosity compared to the first areas.
