Researchers say their prototype produces hydrogen with greater than 99% purity and works in air as dry as 4% relative humidity Donna Lu Researchers have created a solar-powered device that produces hydrogen fuel directly from moisture in the air. According to its inventors, the prototype produces hydrogen with greater than 99% purity and can work... Continue Reading →
