    Abstract: A control system and method for an electric machine includes a first calculation module that receives a modified torque command and a calculated stator flux command and that generates first and second current commands and first and second voltage commands. A voltage magnitude calculation module generates a voltage magnitude based the first and second voltage commands. A reference voltage calculator module generates a reference voltage based on a DC link voltage, an angular stator velocity and the first and second current commands. A flux weakening module generates the calculated flux command based on the angular stator velocity, the reference voltage and the voltage magnitude.

    Abstract: A fuel cell in a fuel cell stack that provides a transition from nested bipolar plates in the active region of the stack to non-nested bipolar plates in the inactive regions of the stack without giving up the reduced stack thickness provided by the nested plates or changing the size of the flow channels. Particularly, the diffusion media layers in the fuel cells are removed in the inactive regions where the bipolar plates are non-nested so that the volume necessary to maintain the size of the flow channels is provided without the need to increase the distance between adjacent MEAs. A thin shim can be provided between the membranes and the plates in the inactive regions to support the membrane where the diffusion media layer has been removed to prevent the membrane from intruding into the flow channels and blocking the reactive flow.

    Abstract: A temperature control scheme for a fuel cell stack thermal sub-system in a fuel cell system (10) that uses a non-linear thermal model and disturbance rejection to provide an optimum stack temperature. The thermal sub-system includes a coolant loop directing a cooling fluid through the fuel cell stack (12), a pump (26) for pumping the cooling fluid through the coolant loop, and a radiator (22) for cooling the cooling fluid outside of the fuel cell stack (12). The system includes a controller (28) for controlling the speed of the pump (26) so as to maintain the temperature of the stack at a desired temperature. The controller uses the thermal model to anticipate a temperature of the cooling fluid out of the fuel cell stack (12) to control the speed of the pump (26).

    Abstract: A system for controlling a fluid flow control device positioned on a surface of a vehicle. The system includes a fluid flow control device, a ground clearance sensor and a controller. The fluid flow control device has a body with at least one surface and an actuation means in operative communication with the at least one surface. The actuation means is operative to alter at least one attribute of the fluid flow control device in response to a control signal. The ground clearance sensor detects a clearance between the surface of the vehicle and a road. The controller has control logic for generating the control signal in response to the ground clearance sensor. The clearance may be a current clearance between the surface of the vehicle and the road and/or a predicted imminent clearance between the surface of the vehicle and the road.

    Abstract: A novel method of altering extruded membrane films for PEM (polymer electrolyte membrane) fuel cells in such a manner that the membrane films swell substantially uniformly in both the in-plane x and y directions when immersed in water or ionomer solution is disclosed. The invention includes cutting a membrane film from an extruded membrane sheet in a diagonal orientation with respect to the membrane process direction of the membrane sheet. The membrane film exhibits reduced internal stress as compared to conventionally-prepared membrane films and allows a more even distribution of pressure in a fuel cell stack, thereby reducing the incidence of swollen membrane-induced failure mechanisms in the fuel cell stack.

    Abstract: A separator plate for a PEM fuel cell (20) and a method of making the same includes providing a sheet of material (64) having through plane passages formed therein. A sheet of graphite (26, 28) is placed on each of a first face and a second face of the sheet of material to form a laminated member. Compressive force is applied onto the laminated member. First portions of the graphite are extruded to flow into the through plane passages (72). An array of electrically conductive pathways (74) through the sheet are created. Second portions of graphite are bonded to each of the first face and the second face.

    Abstract: A dual-redundant propulsion-by-wire control architecture with robust monitoring is presented to increase system availability without compromising safety. The dual-redundant controllers are able to cross-monitor and self-monitor. Self monitoring is effected at the application level and built-in system tests are performed. The monitor functions are set as high priority tasks. The first controller controls operation of a first population system, monitors operation of a second controller, and, self-monitors. The second controller controls operation of a second propulsion system, monitors operation of the first controller, and, self-monitors. Each controller is operable to identify faults occurring in the first and the second controller, and implement an alternate operating control scheme for the respective propulsion system when a fault is identified. The first controller is signally connected to the second controller by substantially redundant communications buses.
