Fuel Cell Revolution | Hydrogen to the Future?

Hydrogen as an alternative fuel cell for automotive has been in development for almost a century, but interest in it started in the late 1960s as in basic explanation a car powered by water, electricity is used to generate hydrogen by electrolysis. The resulting hydrogen is an energy carrier that can power a car by reacting with oxygen from the air to create water, either through burning in a combustion engine or catalyzed to produce electricity in a fuel cell.
