20090162733 | FLOW FIELD PLATE FOR A FUEL CELL WITH FEATURES TO ENHANCE REACTANT GAS DISTRIBUTION - A flow field plate for a fuel cell includes features in the gas input area that enhance gas distribution to the flow field channels. The input area of the flow field plate directs gases from an input manifold to the flow field channels. The input area includes one or more input channels which are defined by input channel walls. One or more features are included within the input area to enhance the distribution of the gas to the flow field channels. The gas distribution enhancement features may provide support for a sealing element to reduce blockage of the channels and/or may provide a path for fluid communication between adjacent input channels. | 06-25-2009 |
20100297526 | CATALYST LAYERS TO ENHANCE UNIFORMITY OF CURRENT DENSITY IN MEMBRANE ELECTRODE ASSEMBLIES - 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. | 11-25-2010 |
20110079551 | WATER TREATMENT CARTRIDGE - A water treatment cartridge, or insert, for use in connection with a water treatment device such as a gravity-fed water pitcher or the like includes a support structure and water treatment material arranged in combination with the support structure. The support structure may, for example, generally enclose the water treatment material, or the support structure may be integrated into the structure of the water treatment material | 04-07-2011 |
20140152580 | MESH PATTERNS FOR TOUCH SENSOR ELECTRODES - An electrode for a touch sensitive device includes micro-wire conductors arranged to define an electrically continuous electrode trunk area, and including branching elements which extend outward from the electrode trunk area. The electrically continuous trunk area is patterned coincident an underlying reference mesh pattern, as are the branching elements. | 06-05-2014 |
