Protonex Partners with Ensign Bickford Aerospace & Defense Company on Next-Generation Fuel Cell Power System


August 11, 2008

DATELINE: SOUTHBOROUGH, MA; Protonex Technology Corporation (LSE: AIM: PTX and PTXU), a leading provider of advanced fuel cell power systems for portable, remote and mobile applications, announces that it has received a $301,000 subcontract from Ensign Bickford Aerospace & Defense (EBA&D), a global leader in energetic systems, to co-develop an advanced fuel cell power source. The goal of the overall program, awarded to EBA&D by the U.S. Army Communications-Electronics Research, Development, and Engineering Center (CERDEC), is to develop a high-performance, 100- watt portable power supply for select military applications.

Under the terms of the subcontract, Protonex will provide a specially designed fuel cell system that will be joined with a fueling subsystem developed by EBA&D to produce an efficient, reliable, next- generation power source. The fueling subsystem designed by EBA&D will convert ammonia borane, a hydrogen-rich chemical compound, into hydrogen. The Protonex fuel cell system will then convert that hydrogen into electricity, which can be used by soldiers to power a variety of military devices and equipment.

The military has selected EBA&D and Protonex to develop this advanced power system to meet the need for a portable power source that can provide long-duration power without increasing soldiers' logistical burden. Fuel cells are able to generate significantly more energy per unit weight than batteries, and have lower heat and noise signatures than combustion-engine generators. For these reasons, the military views fuel cells as a critical power source for the future battlefield.

Protonex will leverage its ongoing work with the U.S. military on high-performance power sources for unmanned aerial vehicles (UAVs) and other portable fuel cell systems to meet the aggressive milestones of this program. "This subcontract is an important design win for Protonex," said Paul Osenar, Chief Technology Officer, Protonex. "EBA&D specifically chose Protonex as a partner for this effort based on the Company's existing military products and our ability to rapidly move forward toward fieldable product. We are looking forward to working closely with EBA&D to make this program a success."
