The vehicles unveiled at the IAA represent a world first in which a fuel-cell-operated electric car uses a lithium-ion battery as an additional energy source that can be externally charged by means of plug-in technology. Through intelligent interplay, the two energy sources drive the electric motor while offering locally zero emissions driving pleasure. The long range, short refuelling time, an output of 147 kW (200 hp) and the latest generation of assistance systems with powertrain-specific features demonstrate, based on the models on show, that the GLC F-CELL will be a family-friendly electric vehicle of high everyday practicality.
For this world first, the Mercedes-Benz engineers cooperated closely with partners from the Daimler competence network to develop a completely new fuel-cell system. Compared with the B-Class F-CELL, which has been on the market since 2010 (fuel consumption: 0.97 kg H₂/100 km/CO₂ emissions, combined: 0 g/km), the overall drive system offers around 40 percent more output. The fuel-cell system is around 30 percent more compact than before, can for the first time be housed entirely in the engine compartment and is installed on the usual mounting points like a conventional engine. Also, the use of platinum in the fuel cell has been reduced by 90 percent. This conserves resources while lowering the system costs - with no compromises in terms of performance.
The lithium-ion battery in the preproduction vehicles on show has a gross capacity of 13.8 kWh and additionally serves as an energy source for the electric motor. For the first time, it can also be charged externally using plug-in technology. An intelligent operating strategy in combination with the fuel-cell/battery system offers maximum efficiency and comfort. Just like the drive motor, the powerful storage battery is space-savingly installed in the rear of the SUV. By means of the 7.2 kW on-board chargers, it can be conveniently charged from a standard household power socket, a wallbox or a public charging station. The charging time is around 1.5 hours if the full capacity is used.
Two carbon-fibre-encased tanks built into the vehicle floor hold around 4.4 kg of hydrogen. Thanks to globally standardised 700 bar tank technology, the supply of hydrogen can be replenished within just three minutes, which is about the same amount of time it takes to refuel a car with an internal combustion engine.
The F-CELL vehicles on show at the IAA are powered by an asynchronous machine with an output of 147 kW (200 hp) and a torque of 350 Nm. As the electric drive requires no propeller shaft, this makes room for one of the two hydrogen tanks, while the second tank is installed under the rear seat bench.
Like the GLC Plug-in Hybrid, the fuel-cell variant comes with various operating modes and drive programs. The drive programs of the GLC F-CELL will include ECO, COMFORT and SPORT. ECO is optimised for low consumption. COMFORT is geared not only for comfort, but also provides ideal climate control. SPORT optimises the hybrid powertrain for sporty performance.
In HYBRID operating mode, the vehicle draws power from both energy sources. Power peaks are handled by the battery, while the fuel cell runs in the optimum efficiency range. The intelligent operating strategy means that the characteristics of both energy sources can be ideally exploited. In F-CELL mode, the state of charge of the high-voltage battery is kept constant by the energy from the fuel cell. Driving almost exclusively on hydrogen is the ideal mode if the intention is to keep the electric range in reserve for certain driving situations.
In BATTERY mode, the GLC F-CELL runs all-electrically and is powered by the high-voltage battery. The fuel-cell system is not in operation. This is the ideal mode for short distances.
In CHARGE mode, charging the high-voltage battery has priority, for example in order to recharge the battery for the maximum overall range prior to refuelling with hydrogen. This mode also creates power reserves for uphill or very dynamic driving.
This is exactly what i want in my new car, just need it in a little smaller form factor. I dont care what people say, the majority is wrong all the effin time. This is best solution. Ev hydrogen hybrid has the best of both worlds and this is the future. Cant wait for them to launch this techh in a smaller car that I can actually afford.
That’s future not 100% electric
Do this car have anything other than an electric drive?
neirad537 as I understand it has only i electric drive/engine but 2 fuel systems which is why I think its such a great design but feel free to correctly me if im wrong about that.
I like the whole concept and idea of the car but its not the ideal car i would buy
It's the ideal car in L.A
So it has less range than the model 3 and only 160kmh top speed. this will fail like the EQC
wrong
C est bien
warning: hydrogen cars are dangerous
Still BMW Is the best
Hydrogen is a bad technology as it’s inefficient, explosive and expensive.
You waste energy doing electrolysis. You also need refuelling stations.
You could argue that so is petrol but that has not stopped us the last 50 years. EVs are no saints either when considered.
That is exactly what an oil company executive would claim.
Well, I have read that lithium-ion battery production is very energy-intensive. So it gave an example that a 100kWh battery will give a potential range of 250 miles and, in order to produce that battery, it will take around 20 tonnes of CO2... So, making a basic calculation that would be 80g CO2/mile. Therefore, EV are not godly as people think today. Coupling these two energy sources could be the optimal energy efficiency in the future.
Well it's better than gas. So what you're saying makes no sense
Energy is never wasted
