2010 Geneva Motor Show

Hyundai Tucson ix35
Vehicle type: Fuel cell SUV concept
Engine: 134-hp fuel cell electric
What's cool: Innovations that bring fuel cell production costs close to those of conventional technology. Metallic separators, or "bipolar plates," in the ix35's fuel cell stack replace traditional separators of graphite, which are expensive to produce. The metallic separators reduce material costs dramatically.
Will it be built? The ix35 shows Hyundai is serious about bringing fuel cell electric vehicles to market. The automaker says it is well along to ramping up fuel cell electric-vehicle production "into the low thousands" by 2012.
Show reaction: Hyundai continues to place its stamp on the fuel cell future, and the Tucson is a realistic version of what could work.
