Key Features of of Protium-300

Suggested Hybrid Lipo Battery

This fuel cell system requires the use of 6S LiPo battery (>100C discharge rated). The ultra-lightweight feature of Protium-300 fuel cell system comes from the elimination of bulky and heavy external humidifiers needed for PEM fuel cell technology. An automated fuel cell stack conditioning protocol maintains the hydration of the membrane. During the stack conditioning event, fuel cell system briefly gets disconnected from the load (approximately 100 milliseconds). A small LiPo battery needs to be used to provide electrical energy to the load during the stack conditioning event.

Operation of the Fuel Cell - Hybrid LiPo Battery For UAVs

The ultra-lightweight Protium-300 fuel cell system works in tandem with the Hybrid LiPo battery. During the startup of the fuel cell, the Hybrid LiPo battery provides the electrical energy to initialize all the electronics. For the power demand up to 300 W, the electrical energy is solely supplied by the fuel cell stack. For events such as take off and emergencies that demand more than 300 W for short durations, LiPo battery provides all the electrical energy needed. For the most efficient use of this tandem power architecture, it is suggested that fuel cell stack to be used for cruising part of the flight and Hybrid LiPo battery to be used during take-off and short duration emergencies.
