While many carmakers have been putting a lot of blood, sweat and tears into electric vehicle technology, some have been dumping a lot of resources into the hydrogen fuel cell.

Haven’t heard much about it yet? Here’s how it works: You fill the tank with hydrogen (instead of gasoline). Then air is pulled in from the intake, delivering oxygen to the fuel stack. Hydrogen is simultaneously pumped into the fuel stack. This causes a chemical reaction that creates electricity, which is then used to power the motor when you hit the gas pedal.
