Applying an electric current reverses the reaction and reverts the metal to its original form. "We are investigating redox mediators as well as exploring new opportunities for sodium-oxygen ...

The sodium/water reaction is a classic ... with two hydrogens bonded to one oxygen. But water is a highly polar molecule, meaning that one side of an H2O molecule (the side facing away from ...

Scientists have developed a fuel cell system which they say could ultimately have enough energy capacity to power regional ...

Their answer is to react liquid metal sodium in a fuel cell with oxygen from the air. “We expect people to think that this is ...

Researchers at MIT have developed a low cost fuel cell that, in tests, has proved able to carry there times as much energy as ...

A new lightweight sodium metal fuel cell could enable practical electric flight by surpassing the limits of lithium-ion ...
