Afterburning hydrogen fuel cell engine for off-road vehicles

We have developed a patent-pending hybrid engine that provides the long range and fuel efficiency of a hydrogen fuel cell with elements of a jet engine for short bursts of peak power.

It is a significant advance on State of the Art zero emission vehicle technology for applications where high power to weight and rugged simplicity are required, like snowmobiles, motorcycles and off road vehicles.


Key Benefits:

Military grade reliability

Our hydrogen fuel cells last 10,000 hours of use before replacement.

Instead of lithium batteries which need replacement after about 1,000 cycles (about 2,000 hours), our invention can use supercapacitors with a 20,000 hour reliability mark.

We achieve this by the hybridization of a hydrogen fuel cell engine with a jet engine for short bursts of extremely high power, reducing reliance on lithium battery technology for high discharge settings.

Jet engines are considered more reliable than gasoline reciprocating engines, and in our invention the jet is only used occasionally.

Maximum power on demand

Our patent pending jet engine hybrid boosts power to a nearly unlimited level at a low weight.

The user can select Eco (fuel cell only) or Sport (fuel cell + jet engine) modes to suit their driving style.

With the added power boost, the light vehicle can climb steep mountains, and tow heavy loads up hills.

Zero emissions

The only exhaust is pure, hot water, which the driver of the vehicle can drink on a long trip.

The jet engine temperature is limited under 1500 C to prevent the formation of NOx (nitrous oxides).

The exhaust steam temperature is much lower than this and exhausted in a safe location like a regular gasoline light vehicle.

Noise is extremely low (just like a battery electric vehicle) when the vehicle is operating in Eco mode.

Additionally, there will be a bypass air intake system to prevent the engine bay containing the fuel cell from being over-cooled by the jet engine (with a fixed bypass ratio). Pat. Pending

Licensing Info:

The afterburning hydrogen fuel cell engine depicted above is patent pending (US/CA 62987294).

We are planning to license the engine at 5% royalty on the sale price of new snowmobiles, quads, dirt bikes, small hovercraft and boats, and small to medium drones. This is a smaller royalty than the 10% which is standard in some industries. We prefer a high volume low margin approach to offset more gasoline snowmobile sales (mandatory minimum sales targets apply for an exclusive license deal).

Technical and engineering support will be included along with drawings and access to the prototype once it is completed.

We also offer the license at a reduced rate to manufacturers who retrofit or upgrade existing gasoline vehicles to zero emission, and who scrap or recycle and do not resell the gasoline motor, as this aligns with our nonprofit objective to reduce greenhouse gas emissions.

For all inquiries, including licensing questions, please contact us.

We are happy to work with you to explain the patent-pending afterburning hydrogen fuel cell engine and determine if it will be a good fit for your company to license and manufacture in your small off-road vehicles (e.g. snowmobiles, quads, dirt bikes, hovercraft, boats and drones).
