Audi's hydrogen-electric hybrid drives 100 km per 1 kg of fuel
The hybrid Audi A7 Sportback h-tron Quattro is able to drive 500 kilometers on a fuel tank, with water acting as an exhaust. The car uses an electric drive with a hydrogen fuel cell as an energy source in combination with a hybrid battery and an additional electric motor on the rear axle. Acceleration to 100 km / h - 7.9 seconds, maximum speed - 180 km / h. Full charging of lithium batteries when hydrogen fuel cells are disconnected will allow another fifty kilometers to pass.
A hybrid car is a car that uses more than one energy source to drive. The main part of modern hybrids is equipped with an internal combustion engine and an electric motor. Audi in this concept decided to move away from the established tradition and use two electric motors, one for the front and rear axles.

Primary uses electricity generated by a hydrogen fuel cell. The principle of operation of the hydrogen fuel cell is in the image below. The element allows for the high-energy H2 + O2 → H2O reaction in a quiet mode, without an explosion, which accompanies the same reaction in a hydrogen internal combustion engine. The result of the reaction is water and energy. The Audi fuel cell itself contains more than 300 individual cells, the core of each of which is a polymer membrane. The catalyst on both sides of the membrane is based on platinum. Voltage ranges from 230 to 360 volts.
1 kg of fuel is needed for 100 kilometers, so that a full tank will allow you to drive 500 kilometers. Filling with hydrogen takes about three minutes, as is the case with cars with an internal combustion engine.
Energy is stored in a lithium-ion battery. After turning off the fuel cell, it will allow you to drive 50 kilometers on a full charge.
