The P250i electrochemically converts propane or natural gas fuels into electrical power. The fuel cell needs no oil changes, has no major moving parts, and requires no maintenance cycles. This means the P250i is capable of providing reliable backup power after years of zero maintenance. The P250i system utilizes voltage sensing leads and a remote temperature probe to detect the actual battery voltage and temperature. This information is used to determine optimal charging and discharging battery voltages. The result: maximum use of battery capacity, life, and system safety. These values can be adjusted to accommodate any battery chemistry.


The ideal backup power source for critical applications, the P250i integrates seamlessly with grid, generator, wind, or solar technologies. The P250i provides the assurance and peace of mind that your critical application will continue to operate during extreme circumstances. The P250i can be added into existing infrastructure with minimal effort, or it can be included in new installations. The system is designed to integrate with batteries, solar charge controllers, DC-DC converters, fused external communications, computers, modems, and other customer electronics. We also provide engineering support to maximize the life-cycle cost for each application.

The D350 system is a back-pack sized 350 Watt Solid Oxide Fuel Cell (SOFC) power generator fueled by propane. The unit electrochemically converts propane into electrical energy. This system is an ideal replacement for remote batteries and battery chargers, especially in advanced ISR or expeditionary warfare applications.

The high energy density of propane results in a significant tactical advantage for the D350 relative to rechargeable batteries. Example: 11 BB-2590 batteries weighing 25 pounds will produce 2.2kWh of energy, while a D350 and 13 pounds of propane, also weighing 25 pounds, will produce 13kWh of energy!


Unlike internal combustion generators which have large moving assemblies and a significant noise signature, the only moving parts in a D350 are the small internal cooling fans. This gives the D350 the noise signature of a computer. The user interface is built into the tethered battery tray (2 BB-2590 slots) which can be used as a BB-2590 battery charger and is equipped with a 5-weight binding post at 14.4Vdc for specific applications. A push of a button commands the system to turn on and provide power in a wide range of environments.

The D350XR was specifically developed for those applications demanding lightweight and rugged power systems. The unit has been proven itself as the power source of choice for the world’s largest military contractors, and is the only lightweight fuel cell in its class that is designed to operate on propane fuel that is readily available anywhere in the world.


The D350XR electrochemically converts propane into electrical power that is used to charge on-board batteries and significantly extend mission duration. The ideal power source for unmanned vehicles, the D350XR helps UAVs fly longer with a more functional payload and allows UGVs to roam further while performing essential tasks, including IED defeat. The D350XR powers sensors for longer persistent stare tasks and eliminates multiple battery changes that draw attention to hidden units.
