摘要： A flowing electrolyte fuel cell system design (DHCFC-Flow) is provided. The use of a flowing oxygen-saturated electrolyte in a fuel cell offers a significant enhancement in the cell performance characteristics. The mass transfer and reaction kinetics of the superoxide/peroxide/oxide ion (mobile oxygen ion species) in the fuel cell are enhanced by recirculating an oxidizing gas-saturated electrolyte. Recirculating oxygen-saturated electrolyte through a liquid channel enhances the maximal current observed in a fuel cell. The use of a oxygen saturated electrolyte ensures that the reaction kinetics of the oxygen reduction reaction are fast and the use of convection ameliorates concentration gradients and the diffusion-limited maximum current density. The superoxide ion is generated in situ by the reduction of the oxygen dissolved in the gaseous electrolyte. Also, a dual porosity membrane allows the uniform flow of fuel (e.g., methane) on the fuel side, without allowing phase mixing. The capillary pressure for liquid intrusion into the gas phase and vice versa is quite large, estimated to be 1-10 psi. This makes it easier to control the fluctuations in gas/liquid velocity which might otherwise lead to phase mixing and the loss of fuel cell performance. In one variation, a dual-porosity membrane structure is incorporated in the system to allow uniform flow of fuel and prevent mixing of fuel with a liquid electrolyte.

摘要： A computer-implemented system and method for tracking entity locations and generating histories from the locations is provided. A tracker is associated with identification data for an entity and placed with the entity. A location of the tracker is determined. Three or more reader systems that receive location readings from the tracker are identified. A reading range of each of the reader systems is determined. An overlapping interrogation zone having a region that is shared by the reading ranges of the reader systems is located. The location of the tracker is calculated based on the overlapping zone. The location and an associated time stamp are stored on a central server with other locations of the tracker and time stamps obtained over time. A request is received for a location history of the entity. A portion of the locations are collected from the central database for the tracker as the location history.
