Patent number: 11967744Abstract: A fuel cell vehicle includes a bypass valve positioned downstream of a compressor and upstream of a fuel cell stack to selectively direct airflow from the compressor to an exhaust bypassing the fuel cell in an attempt to clear a partially or fully obstructed exhaust pipe. The bypass valve may be opened by a controller when an exhaust throttle valve is at or near a wide-open throttle position. The controller may also increase compressor flow and adjust airflow to the fuel cell stack until compressor pressure, speed, or temperature exceed corresponding limits.Type: GrantFiled: February 11, 2022Date of Patent: April 23, 2024Assignee: Ford Global Technologies, LLCInventors: Martin Dale Pryor, Ryan Ma, Craig Michael Mathie

Publication number: 20230268528Abstract: Systems and methods for managing cathode stoichiometry of an electrochemical cell are disclosed. A system may include a fuel cell, a compressor for supplying air to the fuel cell and an oxygen sensor proximate to or downstream of an outlet of a cathode chamber of the fuel cell. An operation speed of the compressor or flow rate of the air may be adjusted by, for example, a controller after receiving data from the sensor regarding the amount of residual oxygen. For example, the operation speed/flow rate may be increased or decreased to achieve a cathode stoichiometry of about 1.00.Type: ApplicationFiled: February 21, 2022Publication date: August 24, 2023Inventors: Martin Dale Pryor, Patrick J. Ford, Craig Michael Mathie

Patent number: 10208656Abstract: A supercharger rotor with reduced rotational inertia may result in increased performance of a supercharger. The rotor may include composite material and may be extrusion molded, injection molded, or otherwise molded or laid-up. In certain embodiments, the rotor may include a core with a central portion and one or more radially extending portions. The core may be extruded or formed of stacked sheets. A molded portion of the rotor, including one or more lobes, may be molded over a corresponding one of the radially extending portions. In other embodiments, a main portion of the rotor includes one or more lobes but no central hole nor a corresponding shaft extending between ends of the main portion. Instead, stub shafts are attached to the ends of the main portion. The increased performance may include decreased noise, decreased cost, increased reliability and/or durability, increased thermal efficiency, an increased power-to-weight ratio, etc.Type: GrantFiled: May 20, 2015Date of Patent: February 19, 2019Assignee: Eaton Intelligent Power LimitedInventors: Martin Dale Pryor, William Nicholas Eybergen

Publication number: 20100196141Abstract: 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 include a first bearing supporting the carrier torque tube and a second bearing supporting the impeller shaft. Embodiments of the invention may also include a seal system.Type: ApplicationFiled: April 12, 2010Publication date: August 5, 2010Applicant: Eaton CorporationInventors: William Nicholas Eybergen, Martin Dale Pryor, James Matthew Brown

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.Type: GrantFiled: December 12, 2006Date of Patent: May 25, 2010Assignee: Eaton CorporationInventors: William Nicholas Eybergen, Martin Dale Pryor, James Matthew Brown
