Hydrogen Motor

Audi A2H2 (2004)

May be the good performance by the combination of a strong 66 kilowatt PEM fuel cell with a 38 kilowatt strong nickel-metal hydride battery.Together they produce a short-term available power of almost 110 kilowatts (150 hp). The electric motor can this energy rate in a torque of up to 425 Newton metres implement - a value, as it otherwise 8-cylinder internal combustion engines. This accelerates the vehicle in 12.1 seconds from 60 to 120 kilometers per hour. The maximum speed of 175 km per hour in some of the series model.

The battery supplies in the energy status for the start of the fuel cell.These supplies in normal operation, the electric motor with power and invites any surpluses with the battery.When accelerating from the battery is also considered energy, while the brake is used for loading.

As fuel is used to PEM fuel cell gaseous hydrogen, in a three-Druckgastank under the trunk on board.The trunk volume is reduced by only a few litres.The tank combines with a pressure of 350 bar 1.8 kilograms of hydrogen, which has a range of 220 kilometers.

With the A2H2 Audi will show that even with a fuel-cell drive sporty driving performance are possible.The combination of fuel cell and battery unit is a concept, as several Japanese car companies in their prototypes implemented.Pioneers are the hybrid vehicles with internal combustion engine and battery, as in Japan has for some years been sold and now also in Europe on the market.

Audi has the construction as well when his prototype fuel cell system as well as the components on the market available components is limited and specific proprietary developments waived, says developer René of Doorn.With a series production and market introduction of fuel cell vehicles expects Doorn until the end of next decade.
