Founded in 2024, Protonas operates in Clean Tech offering air-cooled Polymer Electrolyte Membrane (PEM) hydrogen fuel cells for long-duration backup power, fuel-cell engines for delivery fleets, and lightweight UAV power. It targets telecom networks and critical infrastructure with 500–2,000 W backup systems for multi-day outages, and is developing engines for three-wheeler and four-wheeler delivery fleets that refuel in minutes from standard hydrogen cylinders, while lightweight stacks for drones aim to extend flight range up to three times. R&D focuses on low-cost, air-cooled stacks with fewer parts and simpler balance of plant.
