PROTONEX RECEIVEs Additional $500,000 to Extend Capabilities of Unmanned Aerial 
Vehicle Propulsion Systems 
 
 
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, today announced that it has received an 
additional $500,000 contract award from the U.S. Naval Research Laboratory (NRL) 
for advanced development of high power fuel cell systems for small unmanned 
aerial vehicles (UAVs). This award is an extension of an existing contract with 
the NRL and will focus on incorporating and testing Protonex' advanced fuel cell 
power system within a tactical UAV. 
 
 
Development work under this program will concentrate on advancing the technical 
readiness of the company's UAV fuel cell platform through design improvements 
and stringent testing. The advanced system will be integrated into a new NRL air 
vehicle designed specifically for long endurance. The resulting UAV, powered by 
the Protonex fuel cell system, will be targeted at tactical missions and is 
expected to provide high efficiency and a very low noise profile. 
 
 
This program expands upon a series of efforts by Protonex to transition its fuel 
cell power systems into fieldable UAVs.  At present, battery-powered electric 
UAVs are limited to one to three hours of flight.  Protonex power systems, 
integrated into other small UAVs, have already demonstrated up to four times the 
flight endurance capability of advanced batteries.  With the introduction of 
cutting-edge fuel cell propulsion systems from Protonex, critical missions such 
as persistent surveillance, search and rescue, chemical-biological monitoring, 
and other long-endurance specialty missions can be achieved by smaller, more 
flexible, and cost-effective UAVs. 
 
 
"We've had great success in our previous collaborations with the NRL, and the 
expansion of this UAV program validates those results," stated Dr. Paul Osenar, 
Chief Technology Officer, Protonex. "Protonex looks forward to transitioning 
these advanced systems into fielded military products in conjunction with the 
NRL and other unmanned aircraft system integrators."
