A Closer Look at Hydrogen Refueling

What’s the difference between a hydrogen refueling dispenser and a traditional gasoline dispenser that you see at your local gas station? Not that much, actually. A hydrogen refueling dispenser is used to power a fuel cell electric vehicle (FCEV). But instead of using a combustible gas-powered engine, a FCEV carries a fuel cell onboard that uses hydrogen to power an electric motor which makes the car run.
