Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional batch manufacturing methods for electrochemical cell components, such as gas separators, result in components with low mechanical strength, limited size and shape constraints, high labor intensity, and non-uniformity, making them prone to failure and costly to produce.
Innovation Solution
A continuous manufacturing method that forms a web-form from a web-material suspension on a conveyor belt, advancing it through non-solvent and pore-forming baths to create a non-reinforced electrochemical cell component, allowing for automated production without mesh or fabric reinforcement, enabling efficient and scalable production of components like gas diffusion electrodes and gas separators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If batch manufacturing is used to produce gas separators, then production flexibility is maintained, but mechanical strength and durability are insufficient
Solution Approach 1:
The patent implements continuous manufacturing by passing the gas separator through multiple baths (non-solvent bath, pore-forming bath, washing bath) in sequence on a conveyor system, eliminating batch processing interruptions and continuously producing enhanced components with improved mechanical strength
Solution Approach 2:
The patent replaces mechanical reinforcement (mesh or fabric) with a chemically enhanced polymer structure achieved through sequential bath treatment, where the non-solvent and pore-forming baths create a reinforced matrix that provides mechanical strength without additional structural elements
2Strength
If mesh-structure or fabric is added to reinforce gas separators, then mechanical strength is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The patent removes the mesh or fabric reinforcement from the gas separator structure, relying instead on the chemically enhanced polymer matrix formed through continuous bath processing to provide the necessary mechanical strength
Solution Approach 2:
The patent changes the physical and chemical parameters of the polymer material through sequential bath treatment (non-solvent extraction, pore-forming, washing) to transform the material properties and achieve enhanced mechanical strength without adding mesh or fabric layers
3Ease of manufacture
If conventional batch manufacturing is used, then production setup is simple, but labor intensity and production costs are high
Solution Approach 1:
The patent establishes continuous manufacturing operations where gas separators are continuously processed through multiple baths on a conveyor system, eliminating the start-stop nature of batch processing and significantly reducing labor intensity while maintaining operational simplicity
Solution Approach 2:
The patent combines multiple processing steps (non-solvent extraction, pore-forming, washing) into a single continuous flow sequence on one conveyor system, integrating what would traditionally be separate batch operations into one unified continuous process
4Manufacturing precision
If conventional batch manufacturing is used, then equipment requirements are minimal, but component uniformity is poor
Solution Approach 1:
The continuous manufacturing process ensures uniform treatment of the entire gas separator surface as it passes through each bath, eliminating the variability inherent in batch processing where different areas may receive inconsistent treatment, thereby achieving superior component uniformity
