So how does a FUEL CELL work? The concept is the electrons run through the wire creating the power for the car, and these electrons come from the splitting of ________ from the water (H2O) in the air.
The Electric Car
Electric cars operate using electric motors instead of internal combustion engines found in gasoline cars. An electric motor uses energy from the car's battery pack to produce rotational motion, which enables the car to move. Recharging the battery can be done by plugging the car into an electrical outlet or through specialized charging stations.

Electric cars use a motor but instead of a gasoline-based combustion engine, it uses the power from a rechargeable ________.
Hybrid Cars
Hybrid cars are designed with a purpose: to reduce fuel consumption and decrease harmful emissions. Unlike conventional cars that solely rely on gasoline engines, hybrid cars are equipped with an electric motor that supplements the gasoline engine's power. This electric motor is powered by a battery, which is charged either by regenerative braking (like when the car repeatedly stops or slows down the car) or by the gasoline engine itself.
