Chemochromic Hydrogen Leak Detectors
At NASA, hydrogen safety is a key concern for space shuttle processing. Leaks of any level must be quickly recognized and addressed due to hydrogen’s lower explosion limit. Chemochromic devices have been developed to detect hydrogen gas in several embodiments. Because hydrogen is odorless and colorless and...
Briefs: Green Design & Manufacturing
Because hydrogen is odorless and colorless and poses an explosion hazard, there is an emerging need for sensors to quickly and accurately detect low levels of leaking hydrogen in fuel cells and other...
