Fiat Seicento Hydrogen (2001)

It 'still a prototype, but in 2010 could already be available for the first trials.Il costo per la realizzazione di questa vettura è stato di 20 miliardi con un contributo di 6 miliardi del ministero dell’ambiente. The cost for the realization of this car was 20 billion with a contribution of 6 billion of the Ministry of Environment. Elettra H2 fuel cell represents the evolution of Seicento Elettra, which the new prototype maintains some components like the engine, a propeller electric asynchronous three-phase alternating current and the battery pack which is only trimmed.

The heart of the system of electrical generation fuel cell is placed in the rear area. This is the Stack, the device, powered by hydrogen and dall'ossigeno content in the air, produces electricity to 48 V, with a maximum power of 7 kW. On board the prototype Seicento Elettra H2 fuel cell hydrogen pressure (200 bar) has accumulated six cylinders (9 litres each) arranged behind the back of the front seats.In the future, however, is expected to stoccarlo cylinder placed in the tunnel, instead of the battery pack, thereby restoring the original habitability of the car.

Because the system can work, we must also raise the tension at the Stack .Hence the presence of a converter that the door from 48 V to 216 V value requested by the electric motor that provides up to 30 kW maximum. The traction system of Elettra H2 fuel cell produces electricity to 48 V, with a maximum power of 7 kW value that exceeds the average energy needs of the vehicle when it is used in urban cycle ECE (3.3 kW) and allows you to keep a velocity of 60 km / h.


With the contribution of batteries the maximum speed of the car rises to 100 km / h and acceleration from 0 to 50 km / h happens in 8 seconds.

The autonomy guaranteed by the prototype hydrogen cylinders arranged on board is 100 km which become 140 considering the battery power. The time is fast refueling, about ten minutes, against the 4-8 hours needed to recharge the batteries of Seicento Elettra.



The choice of the seventeenth century as a demo car has its own logic as the technology Fuel Cells aims to cut the environmental impact of cars and, therefore, a car used mainly citizen, as the seventeenth century, is best suited to provide appropriate responses, primarily to environmental problems of our cities. The seventeenth century Fuel Cell powered hydrogen produces no emission of pollutants and generates no carbon dioxide (CO2).
