Scientists have developed a fuel cell system which they say could ultimately have enough energy capacity to power regional electric aircraft. They state that the technology is capable of carrying over ...

What if the future of aviation didn’t rely on heavy lithium-ion batteries or complex hydrogen systems, but instead on a fuel as simple and abundant as sodium? At MIT, researchers are turning this bold ...

Fuel cells powered with the metal could provide a new source of electric power that's far more energy-dense than lithium-ion batteries. A new type of fuel cell that runs on sodium metal could one day ...
