Hydrogen and fuel cell as a propulsion technology for cars
Fuell Cell Vehicle - FCV
Fuel cell electric vehicles FCEV or FCV have a potential to reduce reliance on oil considerably and to decrease emissions contributing to climate changes. FCEV are actually electric cars that don’t need to be charged, but you can simply refuel them like gasoline cars. They look like conventional cars on the outside, but on the inside compose advance technology you cannot find in conventional cars. The most significant difference is in fuel cells that mix hydrogen from fuel tank with oxygen from air and convert it to electricity to power electric engine instead of heavy batteries.
FCV cars produce just clean water.
The only reason why we don't use FCV electric cars is lack of hydrogen refueling stations.
