Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrolysis cells suffer from significant voltage loss due to ports in electrode plates, leading to inefficiencies and bulky designs that are not suitable for compact applications, such as in vehicles, where they require mechanical isolation and frequent maintenance.
Innovation Solution
The electrolysis cell design features a nonconductive housing that encloses positive and neutral electrode plates, minimizing voltage leak paths and using dividers to create precise electrolyte channels, eliminating the need for mechanical barriers and reducing voltage loss through a 'flow barrier' at plate edges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If ports are provided in electrode plates to allow electrolyte flow, then electrolyte circulation is enabled, but voltage loss increases significantly
Solution Approach 1:
The patent removes the ports from the electrode plates entirely, extracting the harmful feature that causes voltage loss. Instead, electrolyte flow is achieved through a separate manifold system that does not penetrate the electrode plates, thereby eliminating the voltage loss pathway while maintaining electrolyte circulation capability.
Solution Approach 2:
The patent introduces a manifold as an intermediary component between the electrolyte source and the electrode plates. This manifold distributes electrolyte to the plates without creating direct pathways through them, serving as a mediator that enables electrolyte flow while preventing voltage loss through the electrode plate structure.
2Loss of energy
If mechanical isolation is used to eliminate voltage leakage, then voltage loss is reduced, but device complexity and bulk increase
Solution Approach 1:
The patent extracts and eliminates the need for complex mechanical isolation structures by redesigning the electrolyte delivery system. By using a manifold that feeds electrolyte without penetrating electrode plates, the design removes the requirement for mechanical isolation components, thereby reducing device complexity while preventing voltage leakage.
3Productivity
If holes are provided in electrode plates for electrolyte circulation, then electrolyte flow is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent removes the holes from the electrode plates, eliminating the manufacturing precision challenges associated with hole alignment and sealing. The electrolyte circulation system is reconfigured to deliver electrolyte through a manifold without requiring precise hole features in the electrode plates, thereby simplifying manufacturing while maintaining circulation efficiency.

AI summary
An electrolytic cell used to electrolyze water and produce hydrogen and oxygen. The cell comprises nonconductive dividers, sandwiching neutral electrodes and designed for rapid flow of electrolyte through the cell to limit voltage loss. A positive electrode plate is disposed in the interstitial space of a nonconductive housing, adjacent to the neutral electrodes. At least one terminal connects to the positive electrode. A negative electrode seals the cell and is sealed with an o-ring. The cell may be mounted to a vehicle or other system using a mounting tab, which optionally also functions as a ground. The cell may use gravitic circulation or a circulating pump to cycle electrolyte. The electrolysis cell may be formed of different dimensions, based on the output needs and application, and may be wired in parallel or in series to suit system needs.
