Both hydrocarbons and nitrogen oxides cause photochemical smog or ozone to result when they are in the presence of sunlight. They are precursors of troposhperic ozone. Once this is formed, the ozone s lifetime is drastically reduced from decades and centuries to only a few hours and days. Electric Vehicles are vehicles whos motors are powered through fuel cells. Fuel cells work through reverse electrolysis , where water can be split into its original elements water and hydrogen by applying an electric current.
Electricity is conducted through the passage of electrically charged ions or atoms.
During the electricity-producing reaction, hydrogen atoms give up electrons at the anode and become hydrogen ions in the electrolyte. Electrons that are released at the anode travel through an external circuit to the cathode. On their journey to the cathode, they can be used to power the electric vehicle. The product water and heat is formed when the electrons and hydrogen ions at the cathode combine with oxygen molecules. Electric vehicles, have a zero tailpipe emission.
