Abstract: A rotor structure for a conical air gap electrodynamic machine has one or more rotor assemblies arranged on an axis of rotation. Each of the one or more rotor assemblies includes magnetically permeable structures positioned radially about the axis of rotation. The magnetically permeable structures include first surfaces confronting the conical air gap that are oriented at an angle to the axis of rotation and second adjacent surfaces that are at an angle to the axis of rotation. The second adjacent surfaces are disposed radially closer to the axis of rotation than the first surfaces. One or more groups of magnetic structures include magnetic material. The one or more groups of magnetic structures include a first group of magnetic structures interleaved with the magnetically permeable structures, a second group of magnetic structures, and a flux conductor shield disposed adjacent to the second group of magnetic structures.

Abstract: An apparatus to control a swelling of a catalyst coated membrane in a fuel cell includes an insulator layer provided at a perimeter of the fuel cell. The insulator layer has a plurality of insulator films and is secured to a flow field plate. The insulator layer has a less compressibility relative to a gasket used in the fuel cell. A method for controlling a swelling of a catalyst coated membrane in a fuel cell includes providing an insulator layer at a perimeter of each of fuel cells in a fuel cell stack. The fuel cell stack is compressed for a predetermined duration when the catalyst coated membrane is in a substantially dry state. Passage of fuel is allowed inside the fuel cell thereby facilitating the catalyst coated membrane to swell. A swollen catalyst coated membrane is allowed to contact the insulator layer.

Abstract: A climate control system is configured to provide at least one of heating and cooling of air in an occupied space of a vehicle. The system includes a thermal energy storage device configured to receive heat from a waste heat source in the vehicle and a heat exchanger coupled between the thermal energy storage device and the occupied space of the vehicle by a coolant loop. The second heat exchanger is configured to transfer heat from at least one of the thermal energy storage device to the occupied space of the vehicle and the occupied space in the vehicle to the thermal energy storage device.

Abstract: Described herein are fuel cell system refueling devices and related systems and methods. In one embodiment, a refueling device includes a fuel handling unit that includes a fuel port and a fuel conveyance unit to convey fuel to a fuel cell system. The refueling device also includes a waste handling unit that includes a waste port and a waste conveyance unit to convey waste from the fuel cell system. The refueling device further includes a communication port and a refueling device controller to establish a communication link with the fuel cell system, such that the fuel cell system directs operation of the fuel handling unit and the waste handling unit.

Abstract: A direct methanol fuel cell integrated process assembly is provided. The assembly includes a housing, a fuel mixing/surge tank and an air/liquid separator integrated to the housing. A vent of the mixer/surge tank is at least proximal to a vent of the separator. The housing further includes at least one condensation pathway integrated along the housing, where the pathway enables exhaust condensates to return to the assembly. At least one exhaust port is provided, which vents directly to a cooling airstream to facilitate exhaust removal. A manifold is also provided, with the fuel valve, a water valve, a fuel pump and a water pump integrated with the housing, where the integrated process assembly reduces an amount of plumbing between the a liquid volume in the mixer and the separator. Further, a water volume of the process assembly is reduced and a form factor of the process assembly is also reduced.

Abstract: A line voltage monitor for monitoring the voltage applied to electrical equipment and for providing an indication or protective disablement of the equipment in the event excessive variations occur in the line voltage. The line voltage monitor includes a steady state voltage sensing means and a transient voltage sensing means for detecting both types of voltage variations.
