Fuel Cell Technology

Our revolutionary fuel cell architecture is reshaping commercial mobility and stationary power generation, with an unmatched combination of power density and fuel efficiency.

Patented eFlow Architecture

Our patented eFlow™ fuel cell architecture is nothing short of a quantum leap in performance, delivering new levels of fuel efficiency, peak power and durability.

At the core of this innovation is our signature trapezoid plate that ensures uniform current and power density across the entire active area, increasing gas velocity down the plate to deliver superior performance and water management, and significant improvements to durability, power and efficiency through our meticulous design and engineering.

What That Means For You

Up to
Lower Fuel Consumption


Fuel efficiency is the top driver for lower total cost of ownership. With our proprietary technology, Loop Energy’s fuel cells are capable of delivering up to 16% better fuel efficiency versus same class alternatives. This can mean significant dollar savings for vehicles and fleet operators, as well as other operational benefits as a result.

Up to
More Peak Power


Loop Energy fuel cells deliver up to 90% more power from the same size stack, almost doubling the vehicle’s drivetrain capabilities. That means without overbuilding the stack, our systems can meet much greater requirements for vehicles that must tackle seasonal challenges, terrain challenges and payload capacities.
Up to
Better Current Density Uniformity


With as much as 10x better current density uniformity across our fuel cell plates, Loop Energy stacks are the living embodiment of our advanced eFlow® technology. This design breakthrough allows our fuel cells to effectively deliver high performance spanning the length of each channel without degradation.
