Electric cars are generally more expensive than gasoline cars
Electric cars produce no pollution at the tailpipe which will contribute to cleaner air in cities
At low speeds, electric cars produced less roadway noise as compared to vehicles propelled by an internal combustion engine
A hydrogen car is an alternative fuel vehicle that uses hydrogen as its onboard fuel for motive power.
There are two ways to get power using hydrogen: Internal combustion engine (ICE) Fuel cell
INTERNAL COMBUSTION ENGINE (ICE)
Very similar to a normal petrol engine
It has two advantages from the fuel cell: It is cheaper than the fuel cell. It can be applied for solving those problems where fuel cells are not a viable solution.

Wankel engine
They have a high production cost. They can´t work with freezing temperatures. They have a long lifetime.
Honda FCX Clarity Ford Edge
It can be obtained through: Thermochemical methods Electrolysis
It doesn´t contribute to carbon dioxide emission.
Fuel cell has a longer lifetime.
Hydrogen doesn´t occur naturally on the Earth. Hydrogen has low energy content per volume unit. It´s necesary build all the infraestructure (refueling stations, pipeline transport…)

A water-fuelled car is an automobile that works only with water(H2O).
ď Ź
Electrolysis process split water into hydrogen and oxygen.
Many water-fuelled cars obtain hydrogen in a mixture of hydrogen and oxygen called “oxyhydrogen” by the electrolysis.
The hydrogen is burned,powering the car and also providing the energy to electrolyse more water.
1-The energy released in combustion is the same that the energy consumed in electrolysis,and there would be no energy to power the car,even assuming 100% efficiency.
2-Efficiency is like 20%.

In 2008 a Japanese company called Genepax said that they had built a car that worked only with water.
