Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In gas recovery systems using stacked electrochemical cells, maintaining a consistent gas flow path width is challenging, leading to increased pressure loss and potential liquid material leakage when cells contain adsorbents or electrolytes.
Innovation Solution
Incorporating a support part between electrochemical cells to create a predetermined gap, maintaining a constant space and preventing liquid leakage by using insulating support parts that cover the stacking surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If electrochemical cells are stacked to provide gas flow path between cells, then gas recovery function is improved, but gas flow path width becomes inconsistent and pressure loss increases
Solution Approach 1:
A support part is introduced as an intermediary component between adjacent electrochemical cells. This support part maintains a predetermined gap between cells, ensuring consistent gas flow path width and preventing pressure loss while enabling the stacked configuration for improved gas recovery function.
2Volume of moving object
If electrochemical cells are stacked closely to reduce size, then device compactness is improved, but liquid material leakage occurs
Solution Approach 1:
The support part serves as a mediator that maintains the necessary spacing between stacked electrochemical cells. This prevents liquid material leakage while allowing compact stacking, thus maintaining both small device size and reliability.
Solution Approach 2:
The support part divides the stacked cell structure into discrete segments with predetermined gaps. This segmentation prevents liquid material from moving between cells while maintaining compact overall structure.
3Manufacturing precision
If support part is added to maintain gap between cells, then gas flow path consistency is improved, but device complexity increases
Solution Approach 1:
The support part is strategically positioned only at specific locations between electrochemical cells where gap maintenance is needed. This localized approach ensures gas flow path consistency without unnecessarily complicating the entire device structure.
