Two-Stage Electric Fuel Cell Compressor

Author: Mark Gee; Peter Davies; Garrett Motion | Honeywell Transportation Systems

Increasingly stringent emissions regulations are promoting alternative energy sources like hydrogen, driving the development of fuel cell propulsion technologies.  Garrett’s Two Stage electric compressor for fuel cells supports this innovative energy source, using a combination of aerospace and automotive technology.

Objectives
• Develop an optimum turbocompressor configuration by working with fuel cell system manufacturers
and by improving upon previous project results.
• Reduce turbocompressor/motor controller costs while increasing design flexibility.
• Develop and integrate the turbocompressor/motor controller into a fuel cell system.
