Backup power
Long-duration backup designed for telecom networks and critical infrastructure. When outages stretch from hours into days, hydrogen keeps running after batteries quit.
DESIGN TARGET: 500–2,000 W · ≈44 kWh
Backup power systemsOne platform. Three jobs.
The same low-cost PEM hydrogen fuel cell architecture, packaged for the places where batteries and diesel fall short.
Mobility
Fuel cell engines in development for three-wheeler transport and four-wheeler delivery fleets across India and other markets — refuel in minutes, run all day.

Fuel cell engines
UAV & drones
Battery packs are expensive and last only 200–300 full discharge cycles. Lightweight fuel cells are designed to extend drone flight range up to three times over.
TARGET: 3× RANGE · LIGHTWEIGHT STACKS
UAV powerTechnology
Electricity from hydrogen. Water as exhaust.
A PEM fuel cell converts the chemical energy in hydrogen directly into electricity — no combustion, no moving parts in the stack, and up to 2 times the efficiency of burning the same fuel. The only byproduct is pure water.
Our R&D focuses on air-cooled stack designs engineered for cost: fewer parts, simpler balance of plant, and manufacturing methods chosen for scale.
| Conversion | Electrochemical — hydrogen + oxygen → electricity + water |
|---|---|
| Efficiency | Up to 2 times traditional combustion technologies |
| Emissions at point of use | None — pure water byproduct |
| Cooling architecture | Air-cooled stacks |
| Refueling | Minutes, from standard hydrogen cylinders |
The company
A veteran team, building in Bangalore.
Protonas was founded in 2024 by Peter David DeVries, a fuel cell industry veteran since 1996 who helped guide the world's first commercially successful air-cooled fuel cells at ReliOn. The company is establishing engineering and manufacturing operations in Bangalore — backed by a seed round led by Transition VC.
