A UGA researcher is part of a team that has created a new, safer part for hydrogen cars.

Hydrogen-powered cars can generally go farther without refueling than battery-powered electric cars. But, one bump in the road to developing hydrogen-powered cars for the consumer market is the risk of fire. Sensors that detect hydrogen leaks can also spark, causing a fire when the flammable hydrogen gas is ignited.

Now, a University of Georgia researcher has built a better hydrogen sensor, that takes the possibility of that ignition out of the picture. Tho Nguyen, an associate professor of physics is a co-principal investigator on the project and co-author of a paper published in the journal Nature Communications.

According to a media release from the University, Nguyen’s new sensor, which he says costs just a few dollars to produce, is also capable of sensing hydrogen in a much smaller concentration, especially important, given the flammability of hydrogen gas.
