Their claims about a ceramic membrane for the fuel cell, and the elimination of the platinum electrode, are certainly interesting on the side of fuel cell technology. In the past, fuel cells had a real lifetime problem (i.e. imagine having to replace the vehicles engine once every three years under normal use, at similar cost, i.e. at least several thousand dollars). However, without knowing the vehicle's mass and performance characteristics, the 2000 km claim isn't very illuminating. Maintaining the hydrogen fueling system is also problematic. It'd be interesting to see what the numbers are for fully loaded semi trucks hauling goods from point A to point B, that seems like a more realistic use, and whether they'd be more economically and energy efficient than electric semi trucks.
