A small assembly plant is churning out around 30 new Ford Focus fuel cell cars as part of Ford's contribution to a Department of Energy initiative to promote development of hydrogen-based technologies. While all the auto companies claim to have small fuel cell fleets, Chrysler says it has 100, Ford is at least humble about it. "Everybody claims to be the leader," said Gerhard Schmidt, Ford vice president of research and advanced engineering. "We are pretty close." The car itself will br 800 pounds heavier than a normal Focus and that's after a carbon fiber trunk and aluminum fenders are added to lower weight. The FCVs (Fuel Cell Vehicles) are estimated to get 50 mph while emitting only water vapor.
