LOS ANGELES - January 28, 2002 - Teledyne Technologies Incorporated (NYSE:TDY) today announced that Teledyne Energy Systems, Inc. (TES) executed a contract modification to deliver a prototype Proton Exchange Membrane (PEM) fuel cell power system to the U.S. Department of Energy under the continuation of work begun by Energy Partners, Inc.

The prototype system will be rated at 7 kW and fueled by natural gas. Scheduled for delivery late in 2002, the unit will be used by the Department of Energy to evaluate the operating characteristics of PEM fuel cell systems under operating conditions similar to those encountered by both vehicle and stationary power plants. The unit will be self-contained with all systems necessary for operation on natural gas. It will also have a state-of-the-art data acquisition system to aid in data collection and analysis.

"We are pleased to continue the work begun by Energy Partners for the Department of Energy," said Robert Mehrabian, chairman, president and chief executive officer of Teledyne Technologies. "Participation in this project will help us gain valuable data and understanding on system design and performance necessary to deliver viable commercial products."

The primary objective of the project is to scale up TES's 3 kW natural gas Stationary Power Unit prototype design to provide at least 7 kW of power. Secondary objectives include improving the system's transient response ability, evaluating various power conditioning options, improving system packaging, and conducting tests in cooperation with the Department of Energy.

Fuel cells produce electricity as a result of the chemical combination of hydrogen and oxygen contained in air. Under development by both the transportation and power industries, they provide higher efficiency and significantly lower pollution emissions than conventional car engines or power plants.
