Crystal boundaries help hydrogen sensors work in hot, humid air

AI Summary

Researchers report that crystal boundaries can help hydrogen sensors remain reliable in hot, humid conditions, where water can otherwise interfere with detection. The work could improve safety monitoring in hydrogen production, storage, transport, and use.

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 active surfaces of hydrogen detectors and prevent them from responding accurately, particularly in hot, moisture-rich environments.
