Fuel-cell technology is an integral part of Daimler’s drive system strategy, thanks to a long operating range and short refuelling stops as well as a broad spectrum of possible uses ranging from passenger cars to urban buses. It is time now for series production, and a new vehicle generation based on the Mercedes-Benz GLC will be launched in 2017.
The Mercedes-Benz engineers joined forces with partners in the Daimler competence network to develop a new, compact fuel-cell system which for the first time fits into conventional engine compartments. Daimler AG has developed an all-new fuel-cell system. Around 30 percent more compact than previously, it can be fully housed in the engine compartment for the first time. The fuel cell developers have also further optimised the performance and operating range. Furthermore, the cost of the innovative technology has been slashed thanks largely to a 90-percent reduction in the amount of platinum used in the stack
Two carbon-fibre-encased tanks built into the vehicle floor hold around 4 kg of hydrogen. Thanks to the globally standardised 700-bar tank technology, the tank in the GLC F-CELL can be refilled at a hydrogen filling station within just three minutes.
The GLC F-CELL also features a large lithium-ion battery as a further innovation of the next-generation fuel-cell vehicles. Rated at around 9 kWh, the battery serves as an additional energy source for the electric motor and can be charged externally by means of plug-in technology for the first time. Together with the further developed intelligent operating strategy, the combination of fuel cell and battery system offers maximum efficiency and comfort. With this set-up, the GLC F-CELL achieves a combined range of around 500 km in the NEDC.
