UNITED DEFENSE, BATTELLE DEMONSTRATE PROTOTYPE FUEL CELL POWER UNIT FOR BRADLEY FIGHTING VEHICLE

Designed to increase fuel efficiency, reduce logistics burden for U.S. Army

Ft. Lauderdale--Battelle and United Defense Industries, Inc. (NYSE: UDI), have teamed to develop and demonstrate a prototype fuel cell auxiliary power unit (APU) on a Bradley Fighting Vehicle.

The system is designed to provide sufficient power to operate the vehicle's electronics indefinitely without engaging the main engine. This fuel cell technology was developed at Battelle's laboratories in Columbus, Ohio, and Richland, Washington, with funding support from the U.S. Army's Tank Automotive Research, Development and Engineering Center (TARDEC) and its National Automotive Center, and integrated by United Defense at its Ground Systems Division facility in Santa Clara, Calif. Both organizations are displaying this technology at the Association of the U.S. Army's Winter Symposium here today through February 18 at the Broward County Convention Center.

Enhancing fuel efficiency while maintaining effectiveness will further enhance the combat effectiveness of the battle-proven Bradley, a key vehicle system for the Army in intense urban combat and rural scenarios. A large percentage of the tonnage in a military deployment is fuel; increasing fuel efficiency enhances military responsiveness by easing the logistic burden.

"By combining the strengths and scientific know-how of our two teams, we hope to provide the U.S. military and the troops in the field with an advanced technical solution to a very real problem," said Steve Kelly, Senior Vice President of Battelle's National Security Division.

"Fuel cell technology offers a silent, clean, state-of-the-art enhancement for current force vehicles such as the Bradley," said Andy Hove, United Defense's Director of Bradley Combat systems. "Integration of Battelle's three-kilowatt fuel cell will not only give Bradley crews a silent watch capability, it will also reduce the stress on the main engine, lower the overall fuel consumption, and reduce the heat level in and around the vehicle."
