Hydrogen Fuel Cell

Hybrid vehicles use 2 sources of energy, namely a combustible engine with a smaller capability, and an electric motor. When the hybrid vehicle is in operation, the low capacity internal combustion engine is continually running. In cases exactly where the hybrid car has to accelerate or climb slopes, the electric motor, powered by a high-ability battery, gets into action and gives the auto the needed kinetic power. The electric motor at the same time powers the automobile as soon as it truly is running at a constant speed for a long time, like on a highway, and the combustible engine is switched off. A traditional braking system dispenses the excess energy that has been generated by the combustible engine, by converting it into frictional heat. However, in contrast to a regular auto, the hybrid auto, although braking or lowering velocity, converts the excess kinetic power into electricity and stores it at the battery. The device that makes this conversion doable is known as a regenerative brake.
