BMW has created a demonstration Fuel Cell Electric Vehicle (FCEV) to test out their latest technologies. The vehicle is based on the BMW 5 Series Gran Turismo and is powered by the latest-generation fuel cell stack, which is being co-developed with Toyota, Hydrogen London partners.
Some of the main benefits of hydrogen powered cars are the range and size of the vehicles. The BMW demo car uses a new type of hydrogen storage tank that enables an operating range of 500km (310 miles). And whilst pure EVs are usually relatively small to conserve weight and be aerodynamic, hydrogen powered cars can be larger. Finally, because the car can be refilled in minutes at a station, FCEVs such as the BMW make for fine long distance machines.
With the help of air and hydrogen fed through the fuel cell, the system produces energy which is stored in an accumulator. The lithium-ion battery with a capacity of 1kWh is enough to add to the torque and propulsion.
The 5 Series GT Hydrogen Fuel Cell can reach 100 km/h (62 mph) from stationary in 8.4 seconds. When running at low loads the fuel cell is 65 percent efficient in turning the hydrogen fuel into forward motion. Under heavy load, that drops to 45 percent, a little better than a diesel engine. A petrol engine is about 36 percent efficient.
BMW states that hydrogen fuel cell technology is a must for our future and that hydrogen is the best resource for sustainable energy. Hydrogen fuel cells leave zero emissions behind, as the only byproduct of a hydrogen fuel cell is water
