The sensor operates using a process called p-doping, where oxygen molecules increase the concentration of positive electrical charges in the active material. When hydrogen is present, it reacts with ...

Scientists have developed a hydrogen sensor that could accelerate the transition to clean hydrogen energy. As the world transitions away from fossil fuels, hydrogen is considered a key player to the ...

This functionality is maintained across a broad temperature range, from standard room temperature up to 120 degrees Celsius (248°F). The new hydrogen sensor underwent rigorous testing in ...

Hydrogen sensor. Credit: Thomas Anthopoulos. As the world moves toward cleaner energy, hydrogen is seen as a key alternative to fossil fuels. However, hydrogen is clear, odorless, and highly ...

When hydrogen is present, it reacts with the oxygen, reversing this effect and causing a rapid drop in electrical current. This change is fast and reversible at room temperature up to 120 °C. The ...

When hydrogen is present, it reacts with the oxygen, reversing the effect and causing a rapid drop in electrical current. This change is fast and reversible, functioning efficiently at room ...

Scientists at The University of Manchester have unveiled a hydrogen ... and reversible at room temperature up to 120°C, making it ideal for real-world applications. The sensor has already been ...

This method can be used to detect hydrogen leaking out of tanks or pipelines, for example. "This sensor could be used to check containers, pipelines or connectors. It would also be possible to place ...

This change reverses as soon as the hydrogen is gone, allowing the sensor to reset and prepare for another detection cycle. The sensor operates efficiently from room temperature to 120°C, making it ...

As U.S. transit agencies increasingly order buses powered by batteries or hydrogen fuel cells, some of these same agencies are beginning to look at trains that use similar technologies.
