    摘要： An exposure indicating apparatus for monitoring air flowing along a flow-through path extending from the external environment through an air purifying respirator cartridge and into a face mask. A processor housing is releasably attached to the flow-through path so that it can be removed allowing ambient air to enter the flow-through path at the attachment location. A reversible sensor with at least one property responsive to a concentration of a target species within an environment is in fluid communication with the flow-through path. A processing device in the processor housing generates a concentration signal as a function of the at least one property of the reversible sensor. An indicator provides an active indication in response to the concentration signal. A flow-through housing may form a portion of the flow-through path. The flow-through housing may be interposed between the air purifying cartridge and the face mask. The reversible sensor may be located in the processor housing, the air purifying respirator cartridge or the flow-through housing. The sensor is coupled to the processing device by a coupler.

    摘要： A nanostructured composite film comprising a plurality of nanostructured elements, wherein the nanostructured elements are either two-component sub-microscopic structures comprised of whiskers conformally coated with a conducting, preferentially catalytically active material or one component sub-microscopic structures comprised of a conducting preferentially catalytically active material, such that the nanostructured elements are embedded in an encapsulant, wherein the encapsulant can be a solid electrolyte. The composite film can be used as an electrode membrane in an electrochemical cell or sensor.

    摘要： Components that include catalyst layers used in membrane electrode assemblies (MEAs), and methods of making such components are described. The catalyst layers yield more uniform current distributions across the active area of the MEA during operation. The catalyst layers may have a uniform catalyst activity profile of a less active catalyst to achieve more uniform current density over the MEA active area. The catalyst layers may have a variable activity profile, such as an activity profile with a varying slope, to compensate for the inherent nonlinearities of catalyst utilization during operation of an electrochemical fuel cell. Desired variable catalyst activity profiles may be achieved, for example, by varying the catalyst loading across the MEA from inlet to outlet ports or by varying the surface area of the catalyst loading or by varying the surface area of the catalyst support elements.
