Changes in military technologies have resulted in an increasing demand for light, mobile, power.
After an intial $3.5 million for development and successful delivery of 10 test units, Protonex Technology has received an additional $3.65 million to continue research from the U.S. Army Research Office (ARO).
The unit, known as the Pulse M250, is a 250-watt portable system. "Proton exchange membrane (PEM) technology ... use a polymer electrolyte and porous carbon electrodes containing a platinum catalyst stacked in a planar configuration. They operate at relatively low temperatures (around 80oC, or 176oF) so they offer quick startup times and reduced wear on system components, which allows for greater durability. They require only hydrogen fuel, oxygen from the air and water to operate. ... Depending on the system size and application, hydrogen fuel for Protonex systems is supplied from one of the following sources: Compressed hydrogen, Metal hydrides, Chemical hydrides, (or) Reformed methanol"
