  • FUEL CELL SYSTEM FOR AN ELECTRIC VEHICLE
    Publication number: 20010049040
    Abstract: The invention is directed to a fuel cell system for an electric vehicle that is driven with (at least among other things) fuel cells, whereby the—preferably but not exclusively air-cooled—fuel cell system is installed such that the dynamic pressure of the relative wind drives the cooling system. A fuel cell stack is preferably located at the radiator of the vehicle and the relative wind directly cools the individual fuel cells.
