Hydrogen-electric hybrid from Audi travels 100 km per 1 kg of fuel Bashny.Net

Hybrid Audi A7 Sportback h-tron Quattro able to travel 500 miles on a tank of fuel, in this case acts as an exhaust water. Uses electric cars with a hydrogen fuel cell as a power source in conjunction with a hybrid battery and an additional motor for the rear axle. Acceleration to 100 km / h - 7, 9 seconds, top speed - 180 km / h. Fully charging the lithium battery when power hydrogen fuel cells will help drive another fifty kilometers.

Hybrid car - a car that uses more than one source of energy for the drive. The main part of modern hybrids equipped internal combustion engine and an electric motor. Audi in this concept has decided to move away from the tradition and use two electric motors, one for the front and rear axles.

The main uses electricity generated by the fuel cell from hydrogen. The principle of operation of the hydrogen fuel cell - the image below. Element allows a high-energy reaction H2 + O2 → H2O in a quiet mode, no explosion, which accompanies the same reaction in the hydrogen combustion engine. The result of the reaction is water and energy. Audi fuel cell itself contains more than 300 individual cells each of which the core is a polymeric membrane. The catalyst on both sides of the membrane is based on platinum. The voltage is from 230 to 360 volts.

1 kg of fuel required per 100 kilometers, so that a full tank will help to drive 500 kilometers. Hydrogen refill takes about three minutes, like in the case of cars with internal combustion engines.

Energy is stored in a lithium-ion battery. After disconnecting the fuel cell will allow it to travel 50 miles on a full charge.
