Solution Overview

Problem

The production of membrane electrode assemblies (MEAs) is bottlenecked by the time-consuming curing process of adhesives, which limits the processing capacity and speed of manufacturing stations, especially for prefabricated MEAs with not yet fully cured adhesives.

Innovation Solution

A device and method that utilize a magazine system to collect and cure MEAs with pivotable receiving elements, allowing for simultaneous processing and application of pressure and heat to accelerate the curing process, thereby increasing production capacity and speed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If adhesive curing is performed sequentially for each MEA, then curing quality is maintained, but production capacity and processing speed are limited

Engineering Contradiction:
Improveproduction capacityVSAvoidcuring time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent divides the MEA production process into distinct segments: a first production line that prepares MEAs with applied adhesive but does not cure them, and a second production line that receives multiple uncured MEAs and cures them simultaneously in a curing device. This segmentation allows the curing operation to process multiple MEAs in parallel, transforming a sequential bottleneck into a parallel operation that significantly increases production capacity while maintaining proper curing quality for each MEA.

Inventive Principle:
Principle #1Segmentation

2Speed

If pressure and heat are applied to accelerate adhesive curing, then curing speed increases, but the curing process remains time-consuming and becomes a production bottleneck

Engineering Contradiction:
Improvecuring speedVSAvoidprocessing capacity
Core Design Contradiction:
SpeedVSProductivity

Solution Approach 1:

The patent merges multiple uncured MEAs into a single batch and combines them with a curing device that applies pressure and heat simultaneously. By merging multiple MEAs into one processing batch, the curing device can apply pressure and heat to multiple MEAs at the same time, accelerating the curing speed for each MEA while also increasing the overall processing capacity. This eliminates the sequential bottleneck where only one MEA could be cured at a time.

Inventive Principle:
Principle #5Merging (Combining)

3Productivity

If multiple MEAs are processed simultaneously, then production capacity increases, but handling and positioning precision becomes more difficult

Engineering Contradiction:
Improveprocessing capacityVSAvoidpositioning accuracy
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent introduces a curing device as an intermediary between the first production line (which prepares uncured MEAs) and the final cured MEA product. This curing device serves as a controlled environment where multiple MEAs can be positioned, held in precise locations, and processed simultaneously with uniform pressure and heat application. The intermediary curing device manages the complexity of handling multiple MEAs, ensuring that positioning accuracy is maintained even while processing capacity is increased through simultaneous operation.

Inventive Principle:
Principle #24Intermediary (Mediator)
