Electrolyser Stack Trolley for Offline Conditioning and Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manufacturing process for solid oxide fuel cells (SOFC) and electrolyzers is hindered by long cycle times required for conditioning and testing, which are time-consuming and incompatible with continuous-flow production, especially in mass-production settings where equipment implementation would decrease production rate and require significant space.
Innovation Solution
A transport and testing trolley system that moves stacked assemblies from the production zone to a conditioning and testing station, equipped with a movable frame, electrical connectors, fluid manifolds, and a mechanical load system to apply vertical compression, allowing for efficient testing and conditioning without manual manipulation, thereby optimizing production efficiency and reducing the risk of component damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conditioning and testing equipment is implemented in the production zone, then testing and conditioning can be performed, but production rate decreases and space requirements increase
Solution Approach 1:
The patent extracts the conditioning and testing operations from the continuous production zone and relocates them to a separate offline station. The trolley transports stacks between production and testing areas, allowing conditioning and testing to occur independently without blocking the production flow, thus maintaining production rate while ensuring quality assurance.
Solution Approach 2:
The trolley acts as an intermediary transport device between the production zone and the offline conditioning/testing station. It carries the stacks and maintains electrical connections, enabling seamless transfer of components for testing without interrupting the production line, thereby resolving the conflict between productivity and reliability.
2Ease of operation
If manual manipulation of stacks is performed during testing, then adjustments can be made, but component damage risk increases
Solution Approach 1:
The system enables self-service operation where the mechanical load system automatically applies vertical compression to the stacks during conditioning and testing. The electrical connectors maintain continuous contact without requiring manual adjustment, allowing the system to perform testing functions autonomously while minimizing handling and reducing component damage risk.
Solution Approach 2:
The patent replaces manual mechanical manipulation with an automated mechanical load system that applies controlled vertical compression. This automated system eliminates the need for operators to physically handle and adjust stacks, reducing the risk of component damage while maintaining the necessary mechanical pressure for testing.
3Productivity
If stacks are transported and tested offline, then production flow is maintained, but preparation time increases
Solution Approach 1:
The trolley is pre-equipped with electrical connectors and mechanical load systems before stacks are placed on it. This preliminary preparation allows stacks to be immediately tested upon arrival at the offline station without additional setup time, maintaining production flow while minimizing preparation time for each testing cycle.
Solution Approach 2:
The trolley is designed as a universal platform that can transport and support multiple stacks simultaneously, with integrated electrical and mechanical systems. This multi-functionality allows the same device to serve both transport and testing preparation functions, reducing overall preparation time while maintaining production flow.

AI summary
The invention relates to a transport and testing trolley (1) for moving and conditioning and/or testing stacked assemblies of electrolyser and/or fuel cell components. The trolley allows to take stacks immediately at the end of an in-zone production, for example an in-line production, to transport them directly to a conditioning and/or testing station and to implement conditioning and/or testing step(s) of said stacks directly on the trolley, without having to manipulate them before said steps.
