Automated Fuel Cell Stacking System for Higher Productivity
Here’s PatSnap Eureka !
Summary
Problems
The manufacturing of hydrogen fuel cell stacks is labor-intensive and not fully automated, leading to increased cycle time and reduced productivity due to manual stacking of numerous components.
Innovation solutions
A system incorporating automated guided vehicles and transfer robots with loading and stacking units, including vision cameras, vacuum adsorbers, and servo-motors, to streamline the stacking process and minimize labor, optimizing the arrangement of working regions for efficient fuel cell assembly and quality control.
TRIZ Analysis
Specific contradictions:
General conflict description:
Principle concept:
If manual labor or local automation is used for stacking fuel cell components, then the device complexity is reduced, but productivity deteriorates and cycle time increases
Why choose this principle:
The stacking system is divided into multiple independent stacking units (first stacking unit, second stacking unit, etc.), each capable of handling specific components. This segmentation allows parallel processing of different fuel cell components, significantly improving productivity while keeping each individual unit's complexity manageable
Principle concept:
If manual labor or local automation is used for stacking fuel cell components, then the device complexity is reduced, but productivity deteriorates and cycle time increases
Why choose this principle:
The stacking units are designed with universal functionality to handle various types of fuel cell components (electrodes, gaskets, gas diffusion layers, membrane electrode assemblies) using the same basic mechanism, reducing overall system complexity while maintaining high productivity

Abstract
A system for stacking fuel cells for a fuel cell stack includes a component part storage region to store the fuel cells, a finished product storage region to store a completed fuel cell stack transferred by an automated guided vehicle, and a plurality of stacking regions disposed between the component part storage region and the finished product storage region, where one side of each stacking region corresponding to the finished product storage region is formed as an entry and exit for the automated guided vehicle for the fuel cell stack, a stacking unit is disposed at each of remaining sides of the stacking region, and the stacking region is supplied with the fuel cells from the component part storage region by the automated guided vehicle to sequentially stack the fuel cells to manufacture the fuel cell stack.
