Rethinking Heavy Duty Fuel Cells

Proven Durability

Our patented cell technology enables a 30,000 hour operating life. No major overhauls, cell, or stack replacements required.

Diesel-like Operability

Our systems are one-to-one diesel replacements. Run them in any climate, on any drive cycle.

High Efficiency

Nimbus' system architecture maximizes cell performance and eliminates the need for a DC/DC converter -- reducing cost, weight and volume while drastically improving efficiency over the entire life of the system.

Zero Emissions

Hydrogen fuel cells do not produce harmful emissions. Powered completely by hydrogen, the only by-products they produce are heat and water.

Respect for the Diesel Engine

Diesel engines have powered the heavy-duty market for over 100 years. And with good reason! Diesel engine technology proved itself as a durable, reliable, low-cost solution to vehicle power generation.
