Eaton's fuel cell product line consists of two product families; the M24 line which is an offshoot of its Roots-type supercharger technology and the centrifugal compressor product line based on proprietary two stage and single stage non-surging technologies. The M24 product has a dual seal configuration specifically engineered for fuel cells to provide a low cost and durable solution for the atmospheric stack market and the mid-range stack market. The centrifugal compressor product uses two back-to-back impellers driven by a common shaft with an external stage-to-stage transfer tube to improve efficiency over a wide operating range and is designed to meet the needs of higher pressure stacks up to a pressure ratio of 2.8. The centrifugal compressor product has the highest system efficiency of any product available on the market.

Fuel cells combine hydrogen fuel with oxygen from air to create electricity without combustion and require auxiliary systems that manage the flow of gases into the fuel cell. Because auxiliary systems, such as the air handling system inside the fuel cell, consume a portion of the electricity produced by the fuel cell, improvements in the efficiency of auxiliary systems enhances the energy efficiency of the fuel cell and the automobiles that are powered by them. The lightweight and compact UQM® motor operates at 24,000 revolutions per minute and is highly efficient.

"We are pleased that Eaton Corporation, a world leader in the design and manufacture of compressors for a wide variety of applications, has expanded their requirements for UQM® motors to drive the compressors in their fuel cell blower product line. As a globally recognized expert in developing advanced engine air management technologies for the transportation industry, Eaton has developed innovative products that meet the air handling requirements of fuel cell developers and we are pleased that our highly efficient drive motors are part of these exciting products", said William G. Rankin, President and Chief Executive Officer of UQM Technologies, Inc.
