Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing steam electrolysis stacks face challenges in uniformly distributing reaction fluid to steam electrolysis cells, leading to performance, safety, and reliability issues due to concentrated fluid supply at central portions, which degrades the overall stack performance.
Innovation Solution
A manifold device with a first and second planar flow path system that guides reaction fluid through intersecting directions, including diffusion, alignment, and mixing portions to uniformly distribute the fluid across multiple unit cells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the reaction fluid is supplied through a conventional manifold block to steam electrolysis cells, then the fluid supply is simple and direct, but the fluid distribution becomes concentrated at central portions rather than uniform across all channels
Solution Approach 1:
The patent introduces a two-dimensional planar flow path system with first and second flow paths extending in different directions within the manifold block. This dimensional approach allows the fluid to be distributed across multiple channels in a systematic manner, achieving uniform distribution without concentrating at central portions. The first flow path distributes fluid in one direction while the second flow path distributes in another direction, creating a comprehensive coverage pattern.
Solution Approach 2:
The manifold block is segmented into multiple flow paths (first flow path and second flow path) that independently distribute fluid to different channels. This segmentation prevents concentration at single central portions by dividing the fluid distribution function across multiple separate pathways, ensuring each channel receives appropriate fluid supply.
2Reliability
If the reaction fluid is concentratedly supplied to a particular channel, then the supply structure is simple, but the performance, safety, and reliability of the steam electrolysis stack degrade
Solution Approach 1:
By configuring flow paths in two different directions (first direction and second direction) within the manifold block, the system achieves comprehensive fluid distribution to all channels. This multi-directional approach ensures reliable and stable fluid supply to each steam electrolysis cell channel, preventing performance degradation while maintaining structural organization.
3Manufacturing precision
If a conventional single flow path is used in the manifold block, then the structure is simple, but the fluid cannot be uniformly distributed to all channels disposed in the width direction
Solution Approach 1:
The patent employs a two-dimensional flow path arrangement where the first flow path extends in a first direction and the second flow path extends in a second direction. This orthogonal or multi-directional configuration enables the manifold block to reach and supply fluid uniformly to all channels disposed in the width direction, overcoming the limitation of single-direction flow paths.
Solution Approach 2:
The fluid distribution function is segmented into multiple independent flow paths, each responsible for supplying specific channels. This segmentation ensures that no single flow path is overloaded and that fluid reaches all channels uniformly, achieving precise distribution control.
