Overview
This project involved designing and building a demonstration-scale aluminum-air galvanic generator for sustainable power generation research. The system converts chemical energy from aluminum oxidation into electrical energy through an electrochemical process.
The generator serves as both a research tool and educational demonstration for sustainable energy concepts.
Technical Implementation
- Structural Design: Acrylic electrolyte tank and system stand fabricated using laser cutting
- Fluid System: Integrated pumps for closed-loop electrolyte circulation
- Mechanical Drive: 3-stage gear reduction system for controlled aluminum feed
- Temperature Control: Sensor monitoring system to maintain optimal electrolyte conductivity and prevent crystallization
- Speed Monitoring: Hall-effect sensor with embedded magnet in shaft collar for rotational speed measurement
Key Challenges & Solutions
- Corrosion Management: Implemented temperature control to optimize reaction rate while preventing unwanted side reactions
- Material Selection: Chose acrylic for visibility and corrosion resistance in electrolyte environment
- Precision Control: Designed gear reduction system for controlled aluminum consumption rate
- Safety: Incorporated monitoring systems to prevent overheating and ensure safe operation
Results & Impact
The demonstrational generator successfully produces electrical power through sustainable aluminum-air chemistry. It has been used for research at both AlumaPower and the University of Waterloo, contributing to the development of clean energy technologies.
This work advanced understanding of galvanic power generation and supported the company's mission of sustainable energy solutions.
