What is the difference between gasoline-powered cars and those powered by fuel cells?

Fuel cell vehicles (FCVs) are different from conventional gasoline- and diesel-powered vehicles in several ways. First, FCVs are propelled by an electric motor instead of an internal combustion engine. This electric motor is powered by electricity provided by fuel cells. Fuel cell vehicles are more energy-efficient and emit less greenhouse gases and pollutants than vehicles powered with conventional fuel. In addition to these benefits, fuel cell vehicles are quieter, and they can provide more power for electrical accessories, such as onboard navigation and control systems. Gasoline vehicles currently have an advantage in terms of driving range. Most gasoline vehicles can travel 300 to 400 miles before refueling, while most current FCVs can only travel about 250 miles. However, scientists are developing technologies that will allow FCVs to travel farther between refills.  more
