Given the current state of the environment, sustainable mobility is undoubtedly vital. And among the myriad of trailblazing solutions Audi is developing, Hybrid fuel cell a.k.a. Audi h-tron is of critical importance. Fuel cell technology offers a wide range of opportunities for sustainable mobility. Combine that with sustainably-produced hydrogen and you have a winner at your hands. So say hello to the Audi A7 Sportback h-tron Quattro technology demonstrator. The vehicle, an epitome of Audi’s efforts for the development of this technology, uses a powerful electric drive with a fuel cell as its energy source together with a hybrid battery and an additional electric motor in the rear. The fuel cell in the A7 Sportback h-tron Quattro concept car is installed at the front, imitating the configuration of the standard A7 Sportback with the combustion engine. Its exhaust system is made of weight‑saving plastic since it only has to handle water vapour. The fuel cell consists of over 300 individual cells that come together to form a stack. The core of each of these individual cells is a polymer membrane which is flanked by a platinum-based catalyst on both sides.

Here’s how the fuel cell system works: the anode receives hydrogen which is then broken down into protons and electrons. The protons move through the membrane to the cathode, where they react with the oxygen present in air to form water vapour. At the same time, the electrons outside the stack provide electrical power. While the complete fuel cell system functions in the voltage range of 230 to 360 volts, the individual cell voltage ranges between 0.6 to 0.8 volts. It must also be noted that the fuel cell operates across a temperature range of 80 degrees Celsius and places higher demands on the vehicle cooling than an equivalent combustion engine. With that being said, the system delivers almost double the efficiency of a conventional combustion engine.

The other notable aspect of the A7 Sportback h-tron Quattro is its plug‑in hybrid concept. It has a lithium‑ion battery that can store energy recuperated from braking and provide substantial power for full‑load boosting. This allows concept car to offer truly impressive acceleration. And on just battery power, the Audi A7 Sportback h-tron Quattro offers a range of up to 50 kilometres. However, in fuel cell mode the A7 Sportback h-tron Quattro can go 100 kilometres with just one kilogram of hydrogen. Long story short, the vehicle’s tank capacity translates into a range of over 500 kilometres. As far as performance goes, this concept vehicle accelerates from 0 to 100 kmph in 7.9 seconds and is capable of a top speed of 200 kmph – atruly impressive feat for a hydrogen-powered car.

The h-tron, along with an expanse of other technological developments, serves to demonstrate one of the primary mainstays of Audi’s operational philosophy. The other is its dedication to serve every need of its customers across the globe. And this is where the Audi Approved Plus programme comes into play.
