Hybrid
The hybrid car has two power sources – an engine and a secondary cell. These sources work respectively or simultaneously according to the driving condition to increase efficiency. Hybrid cars run on battery power at low speeds and switch to traditional internal-combustion at higher speeds.

A fuel cell is a device that converts the chemical energy of a fuel (hydrogen, natural gas, methanol, gasoline, etc.) and an oxidant (air or oxygen) into electricity. A fuel cell operates like a battery. However, a fuel cell does not require recharging, it produces electricity and heat as long as fuel and an oxidizer are supplied.
Fuel cell construction generally consists
