Hydrogen Fuel Cell Storage
2024 · Sustainable Energy · Individual Project
A modular and safe hydrogen storage solution designed for fuel cell applications. This project explores advanced materials, pressure management, and safety controls to enable efficient on-board hydrogen storage for vehicles and stationary systems.
Project Highlights
- Developed a composite storage vessel rated for 700 bar hydrogen pressure.
- Integrated temperature and pressure sensors for real-time monitoring.
- Designed a fail-safe pressure release system to enhance user safety.
- Bench-tested with a PEM fuel cell for validation.
Technical Details
- Tank Material: Carbon fiber reinforced polymer with aluminum liner.
- Volume: 20 liters (usable hydrogen: ~1.7 kg at 700 bar).
- Control System: Arduino-based data acquisition with wireless alerts.
- Safety: Burst disc, solenoid shutoff, and hydrogen leak detection integrated.
Challenges
- Mitigating hydrogen embrittlement in metal liners.
- Ensuring long-term sensor stability under high pressure.
- Balancing weight, cost, and safety for automotive use.
Results & Future Work
- Achieved safe storage and successful fuel cell operation in lab tests.
- Next steps: further reduce vessel weight and integrate IoT remote diagnostics.
