Fuel cell electric vehicles (FCEVs) are powered by combining hydrogen and oxygen to create electricity. The nascent technology could eventually compete with electric vehicles to replace the internal combustion engine.

The science: A catalyst separates hydrogen into protons and electrons, which split and take separate paths. The electrons go through an external circuit which creates an electric flow. The protons are recombined with electrons and mix with oxygen, which create heat and water.
