Fuel Cell Compressor

Rotrex was one of the pioneers in the development of air compressors for fuel cell systems. Close corporation with some of largest fuel cell producers has resulted in a class leading fuel cell compressor designed to boost the next generation of fuel cell applications.

EK10AA Fuel cell compressor

The Rotrex Fuel Cell compressor (”EK10AA”) supplies oxygen to Fuel Cell systems. The ultra compact and lightweight compressor is a combination of a low speed PMSM motor, coupled directly together with the patented Rotrex traction drive spinning a high efficient centrifugal compressor. The result is a class leading air compressor, designed specifically for Fuel-Cell systems.

Key benefits

  • Clean Oil-free, linear and non-pulsing air supply
  • Ultra-compact, lightweight and flexible integration
  • Automotive design – high resistance to shock/impacts
  • Class-leading efficiency

Why Rotrex and Fuel Cells?


Rotrex has existed for more than 20 years and develops, produces and markets centrifugal superchargers for a wide range of industries based on patented traction technology for OEM, OES, and aftermarket companies worldwide.

The EK10AA is a new product to our product portfolio and our acknowledgement to take part of the all important, green energy transition. The air compressor for Fuel Cells is a key component; hence our aim is to assist towards a quick and safe shift from fossil fuels to zero-emission propulsion, ensuring a healthy environment for our future generations.

For the past decade, fuel cell applications has been part of our business, with references to the majority of global Fuel Cell companies.

Although the product is completely new, it is based on our patented traction drive, which has evolved and improved over more than twenty years. With the help from InnoBooster (Article, in Danish) and customer’s projects, the EK10AA is now a reality which we are very proud of!
