The Protium-3000 is a Closed Cathode, air-cooled Hydrogen fuel cell with higher Current density, operational capability
in a wider ambient temperature range, and longer product lifetime than typical Open Cathode fuel cells in the market.

Capable of delivering up to 3000W of net usable power, the Protium-3000 is ideal for applications such as
aerial drones, ground robots, portable power packs, electrical equipment and personal mobility devices.

The Protium-3000 can be set up in less than 1 minute anywhere with no extra tool or equipment required.
Each system also comes with smart electronic controller for autonomous operation, error protection,
remote control, live system monitoring and data logging.
