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.
