Fuel cells are electrochemical devices that directly convert chemical energy from a fuel into electrical energy. Unlike ...

Scientists have uncovered a surprising new healing mechanism in injured cells called cathartocytosis, in which cells "vomit" out their internal machinery to revert more quickly to a stem cell-like ...

Engineers developed a fuel cell that offers more than three times as much energy per pound compared to lithium-ion batteries. Powered by a reaction between sodium metal and air, the device could be ...

This Collection welcomes original research on fuel cell technology, looking at the latest developments in fuel cells’ materials and designs as well as their integration in advanced applications. By ...

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 ...
