  • Patent number: 11103864
    Abstract: An ion exchange membrane has multiple layers of ionic polymers which each contain substantially different chemical compositions. i.e. varying side chain lengths, varying backbone chemistries or varying ionic functionality. Utilizing completely different chemistries has utility in many applications such as fuel cells where for example, one layer can help reduce fuel crossover through the membrane. Or one layer can impart substantial hydrophobicity to the electrode formulation. Or one layer can selectively diffuse a reactant while excluding others. Also, one chemistry may allow for impartation of significant mechanical properties or chemical resistance to another more ionically conductive ionomer. The ion exchange membrane may include at least two layers with substantially different chemical properties.

  • Patent number: 9765443
    Abstract: An electroplating processor has a head including a wafer holder, with the head movable to position a wafer in the wafer holder into a vessel holding a first electrolyte and having one or more anodes. A thief electrode assembly may be positioned adjacent to a lower end of the vessel, or below the anode. A thief current channel extends from the thief electrode assembly to a virtual thief position adjacent to the wafer holder. A thief electrode in the thief electrode assembly is positioned within a second electrolyte which is separated from the first electrolyte by a membrane. Alternatively, two membranes may be used with an isolation solution between them. The processor avoids plating metal onto the thief electrode, even when processing redistribution layer and wafer level packaging wafers having high amp-minute electroplating characteristics.

  • Patent number: 9670586
    Abstract: The present invention provides solid oxide fuel cells, solid oxide electrolyzer cells, solid oxide sensors, components of any of the foregoing, and methods of making and using the same. In some embodiments, a solid oxide fuel cell comprises an air electrode (or cathode), a fuel electrode (or anode), an electrolyte interposed between the air electrode and the fuel electrode, and at least one electrode-electrolyte transition layer. Other embodiments provide novel methods of producing nano-scale films and/or surface modifications comprising one or more metal oxides to form ultra-thin (yet fully-dense) electrolyte layers and electrode coatings. Such layers and coatings may provide greater ionic conductivity and increased operating efficiency, which may lead to lower manufacturing costs, less-expensive materials, lower operating temperatures, smaller-sized fuel cells, electrolyzer cells, and sensors, and a greater number of applications.
