Mercedes-Benz F-Cell - Click above for high-res image gallery

Back in April, Mercedes-Benz announced its plans to begin small-scale series production of a new hydrogen fuel cell-powered automobile called the F-Cell. According to the German automaker, the car is nearly ready to launch, with 200 vehicles slated to be leased throughout the United States and Europe early next year.

The front-wheel drive F-Cell is based on Mercedes-Benz' B-Class platform and uses a 100 kW electric motor that puts out an impressive 214 lb-ft of torque. M-B claims this powertrain will offer comparable performance to a 2.0-liter gas-powered automobile (the run to 60 will take under 11 seconds) while returning the equivalent of 86.6 mpg on the European combined cycle.

Sandwiched under the car's floor will be a 1.4 kWh lithium ion battery that recaptures energy normally lost to braking. We'd also figure that battery pack will provide an even flow of electrons to the motor while the fuel cell hums away silently. Range is quoted at around 250 miles and Mercedes claims a hydrogen recharge time of just three minutes. Expect more details on the car to emerge at the upcoming Frankfurt Motor Show. Full press release after the break.


Mercedes-Benz is launching its first series-produced fuel cell car on the road: the new B‑Class F-CELL. The environmentally friendly electric car has better a performance similar to than a 2,0-litre petrol car and is fully suited for everyday driving. The zero-emission drive system consumes the equivalent of 3.3 litres of diesel per 100 kilometres in the NEDC (New European Driving Cycle). Production of the B‑Class F-CELL will commence in late 2009 with a small lot. The first of around 200 vehicles will be delivered to customers in Europe and the USA at the beginning of next year.

The new fuel cell vehicle offers everything that people expect from a Mercedes-Benz: High comfort and safety as well as no reduction in interior space and boot capacity. Customers will not have to sacrifice any driving pleasure either, because the electric motor has a peak performance of 100 kW/136 hp and a maximum torque of 290 Nm, which is available from the first rotation. It ensures that the B‑Class F-CELL, whose impressive dynamic handling properties are in some cases far better than those of a two-litre petrol car, gets off to an excellent start. Despite these qualities, the zero-emission fuel cell drive consumes the equivalent of only 3.3 litres of diesel fuel per 100 kilometres (NEDC). Thanks to its great range of about 400 kilometres and short refuelling times of around three minutes, the B‑Class F-CELL ensures local zero-emission mobility even for long stretches.

"2009 is the year in which we are establishing further milestones where sustainable mobility is concerned. The B-Class F-CELL is taking on a pioneering role as the world's first fuel cell powered automobile to be produced under series production conditions", says Dr. Thomas Weber, Member of the Board of Management of Daimler AG, responsible for Group Research and Development for Mercedes-Benz Cars.

The vehicle's technological heart is the new generation of the compact, high-performance fuel cell system, in which gaseous hydrogen reacts with atmospheric oxygen at 700 bar to generate a current for the electric motor. The fuel cell system of the B‑Class F-CELL has a very good cold-start capability even at temperatures as low as minus 25 degrees Celsius. The drive system was completely newly developed versus the F-CELL A-Class presented in 2004, with Mercedes-Benz engineers achieving considerable improvements in output, torque, operating range, reliability, starting characteristics and comfort. The B-Class F-CELL now offers driving pleasure and day-to-day suitability at Mercedes level – without local emissions.

As in hybrids with combustion engines, the fuel-cell car uses a lithium-ion battery with an output of 35 kW and a capacity of 1.4 kWh to boost power and recover braking energy. Lithium-ion technology offers several advantages over conventional batteries, including compact dimensions, high performance, great recharge efficiency and a long service life.

The B‑Class F-CELL employs the unique sandwich floor architecture that is well-known from the A- and B-Class. The advantage of this design is that the drive components are located in the sandwich floor, where they are protected and don't take up much space so that the vehicle's interior remains fully usable and a boot capacity of 416 litres is available.

The B-Class F-CELL does not need to fear comparison where equipment is concerned either. Eye-catching features include a bonamite silver paint finish and exclusive light-alloy wheels in a 10-spoke design. In the interior, leather upholstery, seat heating, automatic climate control and the COMAND-system, as well as other features, continue to ensure a high level of comfort.

Same level of safety as in other Mercedes cars

No matter what the conditions, the operational reliability of the B‑Class F-CELL is of the same high level as in Mercedes vehicles with conventional combustion engines. The B‑Class F-CELL's integrated safety concept takes the specific characteristics of the innovative drive system into account. The concept incorporates the expertise from the many years of experience Mercedes-Benz has had with fuel cell drives and high-voltage applications. Mercedes engineers have tested and optimised the drive-specific components' safety in more than 30 additional crash tests.

Network of filling stations required for car's widespread use

With more than 100 test vehicles and a combined total of over 4.5 million kilometres of trial testing, Daimler and Mercedes-Benz have the most extensive experience with fuel cell vehicles of any manufacturer worldwide. The B‑Class F-CELL is further testimony of this technology's high level of development for automotive use. However, a comprehensive network of hydrogen filling stations still has to be set up before locally zero-emission driving can become a widespread reality. To make this possible, Daimler is cooperating with government authorities, energy utilities and oil companies in joint projects in places such as Hamburg, Stuttgart and California.

Mercedes-Benz views the development of electric cars with battery and fuel cell drives for local zero-emission driving as a means of supplementing vehicles with high-tech internal combustion engines. Advanced diesel and petrol engines will remain important for automotive applications for a long time to come - not only for individual mobility in passenger cars - especially over long distances - but, more importantly, for freight transport in trucks. Electric vehicles, on the other hand, will increasingly be used in urban transport.

      i really hope we go all hydrogen in the future....EV's are good but Hydrogen seems more practicle and less taxing on the enviornment
        • 5 Years Ago
        Zamafir is right on.
        Wonder how many KW that fuel cell puts out...probably a lot less than 100KW!!
        And a 1.4KWH battery? LOL...full throttle for maybe 8 minutes or less. But I guess Mercedes knows what they're doing. This isn't a track toy anyway. Sick.

        less taxing in what actual scientific way? 97% of the commercially available hyrdogen comes from fossil fuels. hydrogen fuel cells require lots more rare earth materials than electric cars, they're also less efficient than diesel and electric at current.

        They do cost hundreds of thousands of dollars so I guess their relegation to 40-200 run leases for a year or two then crushing all those huge repositories of rare earth material is less taxing than crushing a hundred thousand cars, or whatever?

        Give me a call when we're not producing hyrdogen from fossil fuels, when the cars aren't using lots of expensive, toxic, rare earth bits, and when they're actually available for... you know... sale.

        Your exact arguments could have been used against EVs not too long ago.

        Electricity comes primarily from fossil fuel powered generating stations.
        The batteries in EV require large amounts of toxic heavy metals.
        Practical, affordable EVs aren't exactly common in the market, either. You can get on a waiting list for a Tesla, if you've got enough cash...

        Stop being such a downer. This is a blog for auto enthusiasts; many of us are not so narrow-minded and we can be enthusiastic about ALL new potential technologies.

        It is nice to see that the world's premier auto manufacturers aren't putting all their eggs in the pure-EV basket. GM, BMW, Honda, Mercedes, and Toyota are making great strides towards producing affordable fuel cell vehicles.

        According to CNET, the fuel cell puts out 108hp, which is 81kW.


        (Just wondering, I live in an urban district, with no garage. Where would I plug in my EV?)

        • 5 Years Ago
        Agreed. Fuel cells seem like the better option by far than the pure EVs people seem to be loving at the moment.
      • 5 Years Ago
      It gets worse. Some research indicates an approximate 75KW fuel cell, sufficient with a 35KW battery (although only 1.4KWH...do the math...2.4 minutes before you're down to 102hp!). And that assumes no parasitic losses, like ac, heat, power steering, radio, etc. Ballard makes one with about 1300w/liter energy density so figure 50 liter fuel cell. Workable, but underpowered.

      I'd just be happy if we could get the A or B class here.
        • 5 Years Ago
        My thoughts exactly! I saw a whole bunch of B-Classes in Toronto, and was jealous. It was extremely dumb of MB to release the R-Class at the expense of the B-Class in the USA. We all know how well that went for them (a huge failure, from what I understand).

        The B-class is VERY popular in Toronto.

      How the hell do you rate "diesel-equivalent" fuel consumption? That has to be even screwier than GM's 230 campaign for the Volt.

      This news is completely meh-inspiring.
