Fuel cells that react liquid sodium metal with air could be the power source required to give electric airplanes much longer ...

When the alkali metals are cut, they initially appear shiny grey but quickly become dull and white as they react with oxygen in the air. This is known as tarnishing. Sodium tarnishes more quickly ...

Many metals react with oxygen to form metal oxides. Potassium and sodium are soft metal which are easily cut exposing a shiny surface which changes to dull rapidly. The change from shiny to dull ...

The sodium/water reaction is a classic ... if there's enough energy, the atmosphere's oxygen reacts with the hydrogen gas, creating a combustion reaction. All of this can be explained simply ...

MIT engineers developed a fuel cell that offers more than three times as much energy per pound compared to lithium-ion ...

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

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