Flexible Container for Activated Aluminum Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aluminum's reactivity with water is hindered by its oxide coating, and activated aluminum is prone to fouling, leading to unpredictable shelf-life and challenges in field applications where logistics and equipment constraints are a concern.
Innovation Solution
A flexible container system that maintains activated aluminum in an inert environment, forming a gas-tight seal to prevent contamination and includes conduits for controlled water introduction and hydrogen collection, allowing for compact storage and expansion to produce hydrogen efficiently under unpredictable conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If aluminum is activated to increase water-reactivity and hydrogen production, then hydrogen yield and reaction speed improve, but shelf-life becomes limited and unpredictable due to fouling by oxygen and water vapor
Solution Approach 1:
The patent extracts the activated aluminum from the harmful atmospheric environment by sealing it in an inert container, removing the source of fouling (oxygen and water vapor) while preserving the activated state for later use
Solution Approach 2:
The patent creates an inert environment inside the container by filling it with inert gas or maintaining vacuum, preventing oxygen and water vapor from fouling the activated aluminum surface during storage
2Reliability
If a rigid container is used to store activated aluminum, then protection from contamination is improved, but portability and adaptability to field conditions deteriorate
Solution Approach 1:
The patent uses a flexible container that can be folded or compressed for easy transport and deployment in field conditions, while still maintaining gas-tight sealing to protect the activated aluminum from contamination
Solution Approach 2:
The container transitions from a compact folded state during transport to an expanded operational state during use, adapting to different operational requirements while maintaining protection
3Reliability
If activated aluminum is stored in an inert environment, then shelf-life and reactability are improved, but device complexity increases due to need for sealing and inert gas management
Solution Approach 1:
The patent combines the storage container, inert atmosphere system, and reaction chamber into a single integrated unit, eliminating the need for separate sealing and inert gas management systems

AI summary
A system for hydrogen formation includes a container and at least one object. The container defines a reservoir and is flexible along the reservoir. The container forms a gas-tight seal between the reservoir and an atmosphere outside of the container. The at least one object includes aluminum in an activated form. The at least one object is disposed in an inert environment in the reservoir, and the activated form of the aluminum reactable to produce hydrogen in the reservoir upon exposure to water.
