As soon as the hydrogen molecule hits the membrane, a catalytic force splits the hydrogen molecule into electrons
and protons. The proton moves through the fuel cell ‘stack’ while the electrons follow an external circuit providing
current to the electric motor and other components of the vehicle. At the cathode side the protons and electrons
recombine and combine with oxygen to form the vehicle’s only tailpipe emission, water.
Types of Hybrid cars.

1 Parallel hybrid: Combine the gasoline or engine or electric motor to run the vehicle. Both the motor or engine
can work together or separately depends upon driving condition.
2 Series hybrid: The gasoline engine acts like a generator, it charges the battery which supply the power to the
electric motor that propels the vehicle.
3 Plug-In hybrid Electric Motor (PHEV): Similar to a parallel hybrid but with a large battery that can be charged
by plugged into an external power source, allowing for longer electric-only driving range.
4 Full Hybrid: It can operate only on the electric motor, the gasoline engine, or a combination of both. It can
also recharge its own battery through regenerative braking and engine power. It is also known as strong
hybrid.
5 Mild hybrid: Use a small electric motor mainly for assisting the gasoline engine, rather than being able to
propel the vehicle only on electric power. They typically offer fuel efficiency improvements but don’t offer
electric only driving.
