Mercedes-Benz F-Cell
As F-Cell Mercedes -Benz refers to the fuel cell vehicles (Mercedes- Benz NECAR ) are manufactured for testing in small batches instead of pure prototypes.
F-Cell version based on the long A-Class ( V168 )
The F- Cell is a small-series fuel cell vehicle from Daimler. Based on a Mercedes -Benz A-Class long-wheelbase ( V168 ) has been developing a compact drivetrain, which takes place entirely in the sandwich floor. As fuel is gaseous hydrogen, which is stored at a pressure of 350 bar in metal / carbon fiber Komposittanks. This is used in a fuel cell stack from Ballard Power Systems for generating electrical energy, this is driving over a nickel-metal hydride battery as an energy buffer to an electric motor.
The Ballard fuel cell delivers 85 kW and 68 kW gross net. The electric motor has an output of 65 kW, which allows an acceleration from 0 to 100 km / h in about 14 seconds. The top speed is electronically limited to 140 km / h. By braking force recovery, an increase in efficiency is possible, especially in stop-and- go operation. Currently, a fleet of 60 F-Cell vehicles for customers in Europe, the U.S. and Asia is being tested.
At the 6th Michelin Challenge Bibendum (October 2004, Shanghai) Daimler took part with two F- Cell vehicles. This led to prices in the following disciplines:
- Integration / Packaging of drive, operation and maintenance
- Emissions ( 2x)
- CO2 emissions ( 2x)
- Consumption over 130 km, minimum speed 70 km / h
- Braking from 80 km / h
- Rally (88 km on public roads ) (2x )
F -CELL "plus" version based on the long A-Class ( V168 )
To Magdeburg Environmental Forum in June 2008, Daimler presented the first A-Class with 700 bar hydrogen storage technology. This vehicle has traveled from Berlin to Magdeburg, since the range was increased by about 70 % to about 270 km through the higher pressure. This version now called Daimler F- CELL "plus" and wants to show the practicality of 700 bar technology that is coming into production cars from 2010 are used.
F-Cell version based on the B-Class ( W245 )
The F-Cell B-Class leads the successor to the Mercedes -Benz F-Cell A-Class the development of fuel cell technology continues. The official presentation date was June 4, 2005., Where, however, only a cutaway model with the most important data was shown. At the IAA 2007, propelled finished copy on the Mercedes " Road to the Future " was among others, as Bluetec ® presents designated models. Also in this version of the compact powertrain is housed entirely in the sandwich floor of the Mercedes -Benz B-Class. As fuel is used at a pressure of 700 bar stored gaseous hydrogen. The Ballard fuel cell has 100 kW gross power and 80 kW net output. Energy storage is a lithium - ion battery is now used. The electric motor now has a capacity of 100 kW.
In the spring of 2008, Daimler images of B -Class F -Cell vehicles released in winter testing in Scandinavia, to demonstrate the cold-start capability of fuel cell vehicles.
2011 Mercedes -Benz announced its own fuel cell production in Vancouver, Canada to build and published further technical details. Thus, the consumption of the Mercedes B -Class F- Cell hydrogen to be 0.97 kg for 100 km, which corresponds to a diesel equivalent of 3.3 l/100 km. The built-in traction battery is used to receive the energy at the regenerative braking and reduces the load of the fuel cell by regulating processes. This technology is indicative of a series hybrid, the fuel cell acts as a range extender.
Cutaway model at the IAA 2009
Mercedes -Benz manufactures the B-Class even under standard conditions. You should go into series production in 2014, when the hydrogen infrastructure is developed. This event has been postponed.
