How it functions [ Return towards  The hydrogen car  ]

Electric vehicles that run on hydrogen have many advantages: 

• They don’t pollute as they only emit water; 
• They have an autonomy equivalent to cars that run on traditional fuels and can go 800 km for the most efficient prototypes;
• Their performances are equivalent to those of our traditional vehicles; 
• “Filling up” with hydrogen takes less than 5 minutes and is as easy as with traditional fuels; 
• They benefit from the high efficiency of the hydrogen chain, fuel cell and electric engine compared to the internal combustion engine.

The electric engine is powered differently depending on driving conditions:

• By the cell alone at stabilized speed on the highway, 
• By the cell and the battery in the case of repeated accelerations, like those in urban driving.

The battery will be recharged by the cell or by the energy recovered during braking, as in hybrid cars.

This flexibility of use really optimizes the use of energy.
