Crystal boundaries help hydrogen sensors work in hot, humid air
Phys.org ·
The Brief · written from 2 sources
- Palladium nanoparticles with grain boundaries promote hydride formation, enabling hydrogen detection without a heater.
- The sensing reportedly works at 80 C and 90% humidity, conditions where water vapour typically hampers hydrogen sensors.
- Reported as relevant to safer hydrogen production, storage, transport and use, where small leaks pose safety risks.
Why it matters
Humidity is a persistent problem for hydrogen sensors, so a heater-free design that works in hot, humid air could make leak detection simpler and more robust in real hydrogen systems.

Hydrogen could play an important role in cleaner energy systems, but even small leaks can create safety risks. Reliable sensors are therefore essential wherever hydrogen is produced, stored, transported or used. A persistent problem is humidity: water molecules can cover the…
