PROJECT TOPICEV Charging, Batteries & Clean Energy
Hydrogen Cell Leak Detector
A hazardous environment concept investigating low-energy spark-proof electronics, catalytic bead sensors, and thermal imaging to safely pinpoint hydrogen micro-leaks in test cells.
Intrinsically Safe Hydrogen Safety Exploration
- ✓Investigates low-voltage non-sparking circuit design principles.
- ✓Combines micro-sniffers with acoustic ultrasound detection to trace high-pressure leaks.
- ✓Enables automatic ventilation triggers before gas reaches lower explosive limits.
The Engineering Challenge
Problem / Objective
Hydrogen is colorless, odorless, highly volatile with wide flammability limits, requiring rapid localized detection without electrical spark risk.
