Hi Bill, No batteries with a fuel cell. The fuel cell generates the electricity that goes directly to the drive motors. United Aircraft has built all the fuel cells for the NASA space program. They are the power sources for the Space Shuttle. I was involved in a fuel cell program with the German Navy for submarines. .......but no batteries. The fuel cells provided all the electricity the sub needed for propulsion, and hotel power. United's fuel cell power plants are suppling peak power generation for Con Edison in New York City, and are emergency power generators for many hospitals and other power critical operations. Buses become a prime user because buses can be maintained at a central location; and refueled at that location. These tend to be pure hydrogen powered machines. Connie
