Lobed Rotor Compressors for Fuel Cell Electric Vehicles

14 May 2018
Source: UQM Technologies, Inc.

New compressor technology supports up to 150 kW fuel cell stacks, addressing the needs of gas compression for medium-duty commercial and non-commercial fuel cell electric vehicles (FCeV).

UQM’s R340 and R410 fuel cell compressor systems were designed for PEM (proton exchange membrane) fuel cell technology. They produce hydrogen flow rates up to 420 cubic meters per hour with a 1.1 pressure ratio and support continuous line pressures up to 180 kPa absolute.

The UQM systems feature Eaton Corporation’s lobed-rotor technology. When compared to a centrifugal compressor, they have a wider efficiency window. They also provide for significant heat and noise reductions over a comparably sized twin-screw compressor currently being utilized in FCeV.
