Electrolysis
Electrolysis is the process of using electricity to break a compound into simpler elements or substances. The electric current that is applied on a material forces its bonded elements or components to break. The elements that have been separated are dissolved or melted.
Electrolysis is the reaction involved in the mechanism of cars that use hydrogen as their source of power. In such cars, the tank is filled with water. Water is made of hydrogen and oxygen. The electric current from the car's engine applies water to separate hydrogen and oxygen.
A fuel cell converts the hydrogen into electricity that is powerful enough to run a car. A fuel cell is a battery in which fuels are stored and consumed as energy.
