The GLC F-CELL represents an important step by Mercedes-Benz in the development of fuel cell technology. It features a totally new fuel cell system which is so compact that the entire system can be housed in the engine compartment for the first time and installed at the same mounting points as a conventional engine. In addition, the use of platinum in the fuel cell has been reduced by 90 percent in comparison to the predecessor vehicle. Consequently resources are conserved, and system costs are cut without impairing performance. Two carbon-fibre-encased tanks built into the vehicle floor hold 4.4 kg of hydrogen. Thanks to globally standardised 700-bar tank technology, the supply of hydrogen can be replenished within just three minutes – as quickly as is customary when refuelling a combustion-engined car.
The lithium-ion battery has a gross capacity of 13.5 kWh and additionally serves as an energy source for the electric motor. Plug-in technology makes it easy to charge via the 7.4 kW on-board charger at a standard household socket, a wallbox or a public charging station – from 10 to 100 percent SoC (State of Charge) in approx. 1.5 hours if the full power is used. Just like the drive motor, an asynchronous motor with an output of 155 kW (211 hp) and a torque of 365 Nm, the powerful storage battery is space-savingly installed in the rear of the SUV.
The innovative plug-in fuel-cell drive combines the advantages of both zero-emission drive technologies and, thanks to its intelligent operating strategy, continuously optimises the use of both energy sources in line with the current operating situation. This is also influenced by the selected drive program: ECO, COMFORT or SPORT..
There are four operating modes:
– HYBRID: 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.
– F-CELL: the state of charge of the high-voltage battery is kept constant by the energy from the fuel cell. Only hydrogen is consumed. This mode is ideal for steady cruising over long distances.
– BATTERY: 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.
– CHARGE: 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 or to create power reserves.
– In all operating modes, the system features an energy recovery function, which makes it possible to recover energy during braking or coasting and to store it in the battery.
The battery and all components containing hydrogen are governed by particularly stringent safety standards typical of Mercedes. Alongside safety in the event of a crash, all Mercedes-Benz vehicles undergo additional component tests at system level that go far beyond the usual tests. The powertrain components and hydrogen tanks of the F-CELL pre-series vehicles are space-savingly and safely housed in the engine compartment as well as in the vehicle underbody.
Mercedes-Benz’s safety assistance systems are also all on board the GLC F‑CELL. Their sensors have an additional purpose in vehicles that run purely on electric power in that their signals assist the powertrain control with the selection of a range-preserving, efficient strategy for using the on-board energy sources. The energy employed for accelerating the car is used intelligently, taking account of the route characteristics, topography and traffic situation. The driver can always set other priorities, of course, but subtle hints inform them of what they can do intuitively to optimise the vehicle range.
Despite the extraordinary powertrain concept, the GLC F-CELL boasts the everyday practicality and comfort people have come to expect from a Mercedes‑Benz. Even the luggage compartment remains unchanged, with the exception of a minimal step, and the rear seats are only slightly higher positioned in order to make space for the hydrogen tanks. The climate comfort in the GLC F-CELL is on a par with conventional vehicles, and the pre-entry climate control based on mains charging current is an intelligent way of safeguarding the vehicle’s range. At cooler temperatures, the vehicle will make energy-efficient use of the waste heat from the fuel cell in order to optimise the energy balance of the vehicle.
