Washington, D.C. - Ford has unveiled what it calls the world's first drivable fuel cell hybrid electric plug-in, which combines an onboard hydrogen fuel cell generator with lithium-ion batteries. The Ford Edge fuel-cell hybrid is built on a flexible powertrain architecture, enabling Ford to use new fuel and propulsion technologies as they develop, without redesigning the vehicle.

The company says the vehicle, which uses the new HySeries Drive, delivers more than 5.7 L/100 km (49.5 mpg Imp) with zero emissions. If the car is driven less than 80 km per day, the average jumps to more than 2.9 L/100 km (97 mpg Imp).

Quote from article:
The system uses a hydrogen fuel cell supplied by Ballard Power Systems of Burnaby, B.C. The company says that, "clearly, many significant technical hurdles need to be overcome before a vehicle such as the Edge with HySeries Drive can become a reality. Fuel cell vehicles remain expensive, costing millions of dollars each. And the single biggest hurdle to plug-ins remains the cost of lithium-ion batteries. Much work also needs to be done to make fuel cells more durable and to create a hydrogen infrastructure."
