Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hydrogen generation systems through water electrolysis suffer from fluctuating production rates and require oversizing to maintain sufficient output, leading to inefficiencies and potential gas segregation, which is not compact or lightweight.
Innovation Solution
A system where the fluid flows alternately through lower and upper openings between compartments, forcing vertical movement to prevent gas-liquid segregation, ensuring all plate surface area is utilized for electrolysis, and using plates with only one type of opening to stabilize production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the device uses parallel vertical plates with sealed cells for water electrolysis, then hydrogen can be generated through electrolysis, but the hydrogen production rate decreases over time due to gas-liquid segregation
Solution Approach 1:
The patent introduces dynamic fluid circulation where the electrolyte solution is continuously pumped through the plates in a cyclic manner. This dynamic flow prevents gas-liquid segregation by constantly moving the liquid level and ensuring uniform distribution of reactants across all plate surfaces, thereby maintaining stable hydrogen production rates over time.
Solution Approach 2:
The patent implements continuous circulation of the electrolyte solution through the plates using a pump system. The fluid continuously flows from the bottom of one compartment to the top of the next, ensuring that the electrolysis reaction continues uninterrupted and uniformly across all plate surfaces, preventing the decline in production rate that occurs in static systems.
2Productivity
If the device is oversized to maintain sufficient hydrogen production rate, then production stability is improved, but the device size and weight increase
Solution Approach 1:
The patent changes the flow parameters by introducing controlled circulation of the electrolyte solution. By optimizing flow rate, pressure differential, and fluid velocity through the plates, the system achieves efficient electrolysis without requiring oversized dimensions. The parameter optimization allows compact device design while maintaining high and stable hydrogen production rates.
3Area of stationary object
If the plates include both lower and upper openings, then fluid can flow through, but gas-liquid segregation occurs and not all plate surface area is utilized for electrolysis
Solution Approach 1:
The patent segments the plate openings into two distinct types: lower openings at the bottom of each compartment and upper openings at the top. This segmentation creates a unidirectional flow pattern where fluid enters through lower openings and exits through upper openings, ensuring that the entire plate surface area is uniformly utilized for electrolysis without causing gas-liquid segregation.
Solution Approach 2:
The patent transitions from a two-dimensional opening arrangement to a three-dimensional flow pattern by positioning openings at different vertical levels. The fluid must move vertically through the plates from bottom to top, creating a multi-dimensional flow path that maximizes contact between electrolyte and plate surface while preventing gas accumulation that would occur in horizontal arrangements.

AI summary
The present invention relates to a generator (1) of hydrogen by electrolysis, which can be used in any industry using a combustion engine, in particular the energy, automotive, maritime or rail industries. In the generator (1) according to the invention, the fluid is forced to follow a path (100) with ascending and descending movements in order to avoid any separation of the liquid water and the hydrogen and the oxygen created by the electrolysis. The system serves to considerably reduce the emission of CO2 as well as the consumption of fuel.
