Solution Overview
Problem
The efficiency of ion supply from the intermediate chamber to the cathode and anode chambers in three-chamber electrolytic cells is limited, necessitating an enhancement in ion transport mechanisms.
Innovation Solution
Incorporating a spacer with a cathode-side grid and an anode-side grid in the intermediate chamber, where the cathode-side holes and anode-side holes are aligned in one direction but shifted in a perpendicular direction, guiding the electrolytic solution to meander and enhance ion supply by alternately directing it through the chambers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional three-chamber electrolytic cell is used, then the structure is simple, but the ion supply capability from the intermediate chamber to the cathode and anode chambers is limited
Solution Approach 1:
The spacer is divided into two separate grids: a cathode-side grid with cathode-side holes and an anode-side grid with anode-side holes. These grids are arranged in different positions (shifted in the second direction) to create distinct ion transport pathways to the cathode chamber and anode chamber respectively, thereby enhancing ion supply capability through segmented functional zones
Solution Approach 2:
The invention introduces a staggered arrangement of holes in the second direction (perpendicular to the first direction), creating a three-dimensional meandering flow path for the electrolytic solution. This dimensional shift transforms the conventional linear flow into a multi-directional meandering path that increases the effective ion transport area and improves ion supply efficiency
2Productivity
If the electrolytic solution flows directly through the intermediate chamber, then the flow path is short, but the ion supply efficiency is limited
Solution Approach 1:
The electrolytic solution flow path is transformed from a straight line into a meandering curved path through the staggered arrangement of cathode-side holes and anode-side holes. This curvature in the flow path increases the interaction time between the electrolytic solution and the ion exchange membranes, thereby improving ion supply efficiency despite the increased path length
Solution Approach 2:
The electrolytic solution alternately flows through cathode-side holes and anode-side holes in a periodic manner due to the staggered grid arrangement. This periodic flow pattern creates multiple opportunities for ion transport to both chambers, enhancing overall ion supply efficiency through repeated cyclic action

Implementation Method 1
a cation exchange membrane and an anion exchange membrane that are different from each other
Implementation Method 2
When electrolysis takes place in the intermediate chamber, cations are supplied from the intermediate chamber to the cathode chamber, and anions are supplied from the intermediate chamber to the anode chamber

AI summary
In a spacer of an intermediate chamber in an electrolysis vessel, a cathode-side hole that is arranged in a cathode-side grid and an anode-side hole that is arranged in an anode-side grid and is positioned side-by-side with the cathode-side hole with each other in a first direction are misaligned with each other in a second direction that is orthogonal to the first direction. The cathode-side grid and the anode-side grid guide an electrolytic solution flowing into the intermediate chamber from one side of the second direction toward the other side of the second direction while allowing the electrolytic solution to flow along a serpentine course in the first direction by alternately guiding the electrolytic solution to the cathode-side hole and the anode-side hole which are misaligned with each other in the second direction.
