Hydrogen fuel cell range extension for electric vehicles.
AEI's patented on-board fuel cell keeps the battery charged while you drive — doubling effective range without stopping to plug in. Proven on the road, protected by six patents, and ready for trucks, buses and fleet vehicles.
The system
Drive further. Charge less.
On-Board Charging
The fuel cell recharges the vehicle's battery while driving — the same proven range-extension approach demonstrated on the MG4 concept.
700km+ Range Extension
Proven range extension on the road. Drive further between stops, without waiting at a charge point or carrying extra batteries.
Green Hydrogen Powered
Runs on green hydrogen produced by AEI's containerised production units — a fuel supply you control, not one you queue for.
Zero Emissions
The only byproduct is water. No diesel fumes, no particulates, no compromise on emission zones or clean-air mandates.
Fleet-Friendly
Vehicles keep their original electric drivetrain — the fuel cell simply extends it, so fleets re-fuel in minutes instead of charging for hours.
Patented Technology
Six patents with 18 claims protect the system — a defensible platform for manufacturers and fleet operators alike.
How it works
Hydrogen in, kilometres out
Hydrogen On Board
The vehicle carries green hydrogen in certified on-board storage — refuelled in minutes, anywhere AEI fuelling is available.
Fuel Cell Generates
The fuel cell converts hydrogen to electricity on the move, with water as the only byproduct.
Battery Stays Charged
Generated power feeds the traction battery continuously, keeping state of charge high across the route.
Range Extended
The vehicle drives beyond its plug-in range — proven at 700km+ on the MG4 concept, without a single charging stop.
Put fuel cell range extension in your vehicles
The system is available to vehicle manufacturers and fleet operators through the AEI licensing program — or talk to us about a proof-of-concept for your platform.
