Protonex to Exhibit New Portable Power Military Products at the AUSA Annual Meeting & Exposition


DATELINE: SOUTHBOROUGH, MA; Protonex Technology Corporation (LSE: AIM: PTX and PTXU), a leading provider of advanced fuel cell power systems, today announces that it will exhibit several of its new portable power military products at booth #402 at the upcoming Association of the United States Army (AUSA) Annual Meeting & Exposition in Washington, DC, October 5-7, 2009.

The portable power systems on display at AUSA will include:

o M250-CX Portable Battery Charger: a 250 watt portable power system designed to meet the stringent demands of a wide range of military battery charging and auxiliary power unit applications. The unique design combines advances in fuel cell energy conversion and battery charging technology into one complete product solution to provide significant performance benefits over incumbent solutions.

o SPM-611/612 Soldier-Worn Power Managers: advanced power managers designed to dramatically reduce the number and variety of batteries needed by a soldier, while actively monitoring and managing power usage to assure mission success. This intelligent power management system combines leading edge advances in ultra high efficiency power conversion, equipment power management, solar support and energy harvesting technology to offer benefits that are currently unavailable to military users.

o BPM-602 Battlefield Air Operations Power Manager: an advanced power manager designed to efficiently couple a diverse set of energy sources to power consuming devices. This intelligent power management system functions similarly to our SPM product line but handles high power devices such as laser designators and high power radios.

o UAV-C250 & UGV-C250 Advanced Propulsion Power Sources: high-performance ultralight power systems, designed to significantly increase the endurance capability of UAV and UGV missions. Coupling fuel cell stack technology that can achieve 1,000 watts per kilogram with an advanced chemical hydride fueling technology to increase energy density, the unique power systems enable long duration missions not previously feasible.

"The products we are exhibiting at this year's AUSA are designed to dramatically reduce soldiers' logistics burden, along with their carry weight and bulk, and built to significantly lower operational life cycle costs for a wide range of military applications," stated Greg Cipriano, VP Marketing and Military Development for Protonex. "These new products meet specific portable power demands of military field use and greatly expand our ability to provide innovative, high value power solutions that are currently unavailable with advanced batteries or alternative technologies."
