Honeywell Launches Industry-First Electric Compressor for Honda Clarity Fuel Cell Vehicle

ROLLE, Switzerland – June 14, 2016 – Honeywell (NYSE: HON) Transportation Systems has drawn upon its engineering competencies in the automotive and aerospace industries to create a new two-stage electrical compressor used by Honda Motor Company for its hydrogen-powered Clarity Fuel Cell vehicle.


Increasingly stringent CO2 emissions and the need to reduce dependency on fossil fuels are quickly creating demand for alternate sources of energy. Hydrogen fuel cell vehicles are one alternative for providing sustainable, zero-emissions transportation.

As a leader in turbocharging technology for more than 60 years, Honeywell is using its aerospace expertise and resources to drive industry innovation forward. The compressor represents a fusion of aerospace and automotive competencies offered at a lower cost structure and quality level that matches the needs of the automotive industry.

The two-stage electrical compressor is an example of how Honeywell is supporting the industry’s pursuit of improved fuel economy and emissions with innovations integrating a new era of electric products with traditional mechanical applications. Continued hybridization and fuel cell development will feature Honeywell hardware as well as software to develop high-performance powertrain and vehicle systems that are attractive to customers and reflective of increased fuel economy and emissions regulations around the world.

Honda recently announced the Clarity Fuel Cell will feature an anticipated U.S. EPA driving range exceeding 300 miles and a refueling time of about 3-5 minutes.

Benefits of the Honeywell TwoStage Electric Compressor for Fuel Cells

  • Compact Packaging – Honeywell’s TwoStage Electric Compressor eliminates previous powertrain sizing issues typically associated with fuel cell vehicles. Honeywell’s high-pressure technology helps the Clarity Fuel Cell retain the interior cabin space of a true 5-passenger sedan by reducing the overall size of the fuel cell stack to one which is comparable to a V-6 engine. According to Honda, the Clarity’s fuel cell stack is 33 percent more compact than its predecessor.
  • Unequaled Performance – An industry first, the two-stage Honeywell compressor operates at a maximum of 4 bar (400 kPa) and has a continuous rating maximum of 20 kW – more than double the power density of comparable stacks available today while being highly efficient, lightweight and extremely compact. Honda reported that the Clarity Fuel Cell will have a 60 percent increase in power density compared with the outgoing Honda FCX Clarity.
  • Industry First Air Bearings – Honeywell has achieved an automotive first by adapting its existing air foil bearing technology from its aerospace portfolio. These bearings are cooled by the machine’s own compressed air eliminating the potential for poisoning the fuel cell with any oils or greases and helping ensure zero emissions.
  • Unique Aerodynamics – Honeywell has developed a unique aerodynamic configuration using aluminum wheels and housings to assist in critical high power density performance. The high speed aero design reduces mechanical losses and exceeds 70 percent peak efficiency providing the required performance at low speed operating points as well as at peak power.
  • Cost – An important part of the equation was making the cost of the technology affordable for automotive use. Honeywell has transferred aerospace grade technology for air bearings and high speed motor design to the automotive domain. These technologies meet stringent automotive quality standards and allow for high-volume sales.

 Executive Quotes

Honeywell Transportation Systems President and CEO

“This new two-stage electrical compressor for fuel cells draws upon Honeywell’s deep experience with electromechanical systems and our leadership positions in both the automotive and aerospace industries. The Honeywell solution is the ultimate in operational efficiency supporting new levels of performance while bringing to market new technology like oil-less air foil bearings to help increase the durability and reliability of the overall system.

“The ability to draw upon Honeywell Aerospace for the benefit of our automotive customers really differentiates Honeywell from its peers. The resources we share within our aerospace group allowed us to present an already researched and developed compressor solution that could be readily adapted for automotive use in a relatively short time frame. This internal partnership along with the more than 60 years of boosting experience at Honeywell Transportation Systems means Honeywell is well-positioned to help the automotive industry develop the next generation of mechanical and electric boosting systems for gas, diesel, hybrid and fuel cell powertrains.”

Craig Balis, Honeywell Transportation Systems Chief Technology Officer

“The premise is simple, just like an internal combustion engine, hydrogen fuel cells need to be fed air to function efficiently. We have been developing electric products for more than a decade as the industry’s attention has turned to reducing emissions and finding the commercial and regulatory value in technologies enabling those efforts. I fully expect Honeywell’s technology portfolio supporting our transportation, aerospace and automotive software disciplines will play a key role in traditional and advanced powertrain development in the years ahead.”

From electrification of the Aircraft to Automotive

For more than two decades, Honeywell has been active in research and development of high speed electric aerodynamic technology. From aerospace to automotive turbochargers, Honeywell continues to develop electrification technologies that shape the future of transportation.
