An electrically driven supercharger produced by Eaton Corp. will be used in a fuel cell vehicle made by Shanghai Automotive Industries Corp. for the 2010 Shanghai World Expo.

The small-scale supercharger, called a fuel cell cathode blower, has been combined with a brushless motor and moves air through the fuel cell stack, where oxygen in the air combines with hydrogen to generate the electricity that powers the vehicle.

SAIC plans to supply 20 hydrogen-powered vehicles to the 2010 event.

Eaton's Automotive Group, of suburban Detroit, supplies powertrain, emissions and safety components for light and commercial vehicles.
