AI Technical Summary

Technical Problem

Existing electrolytic cells with diaphragms are expensive and require strict maintenance, while membraneless cells face challenges with laminar flow requirements, complex design, and reactant mixing issues, especially with gas/liquid mixtures, leading to difficult product purification and undesirable reactions.

Method used

A membraneless 3D electrolytic cell design with a solid body containing a central cavity, housings, and ducts for separate electrolyte and reactant supply, allowing reactants to be selectively supplied to the anode and cathode without laminar flow, enabling easier product separation and purification.

Benefits of technology

The design facilitates easy operation and effective purification of reaction products by preventing mixing at the anode and cathode, reducing maintenance needs and simplifying the cell's design complexity.

Abstract

The present invention relates to a membrane-free electrolysis cell comprising a solid body (1) containing a central cavity (2), two housings, at least one secondary cavity (2'), at least one duct (5) for providing a material, two ducts (6, 7) for receiving two electrolyte streams and at least one supply duct (8). The cell configuration allows materials, particularly reactants, to be selectively replenished to either the anode or cathode separately from the electrolyte flow.
