Abstract: A multi-stage fuel cell centrifugal compressor system comprising a motor, including a shaft, and a compressor connected to the motor. The compressor includes a first stage inlet; first housing fluidly connected to the first stage inlet; and first impeller driven by the shaft for imparting fluid flow through a first stage of the system. The compressor further includes a first stage outlet fluidly connected to the first housing; a second stage inlet; a second housing fluidly connected to the second stage inlet; a second impeller for imparting fluid flow through a second stage; a second stage outlet fluidly connected to the second housing; and a pipe extending between the first stage outlet and the second stage inlet. The pipe fluidly connects the first stage outlet to the second stage inlet, thereby directing at least a portion of fluid from the first stage to the second stage of the system.

Abstract: The invention provides a fuel cell compressor system that comprises a motor, including a motor shaft driven by the motor; a drive housing at least partially surrounding the motor shaft; a first gear set driven by the motor shaft; a carrier torque tube driven by the first gear set; and an impeller. The impeller includes an impeller shaft driven by the second gear set, so that the impeller shaft is configured to rotate at a speed greater than motor speed. Embodiments of the invention may also be used with a multi-stage compressor that allows, for example, first and second impellers to rotate at different speeds. Embodiments of the invention may also include removal of a gear set driving the carrier torque tube or the impeller shaft, so that the impeller shaft speed is divided between one or more bearings supporting the carrier torque tube and one or more bearings supporting the impeller shaft.
