Abstract: The presently disclosed subject matter relates to devices, systems, and methods of producing an improved fluid flow assembly and liquid/gas diffusion layer in solid polymer electrolyte electrochemical cells. In one aspect, a fluid flow assembly for a polymer electrolyte water electrolyzer includes a flow field having an inlet, an outlet, and a plurality of discrete lands arranged within the flow field. A liquid/gas diffusion layer is positioned in communication with the flow field between the inlet and the outlet, the liquid/gas diffusion layer having a solid substrate through which a plurality of pores is formed. The disclosed bipolar plate flow field and liquid/gas diffusion layer could work together or separately with other types of porous transport layers or bipolar plates to enhance the water/gas transport. In these configurations, the lands can be arranged and configured such that the plurality of pores are substantially unobstructed by the lands.

Abstract: Logical, safe, personalizable, and user friendly computer user interfaces may include: (a) plural branches; (b) plural sub-branches associated with the branches; and (c) an interface control that includes: a branch locking interface, a sub-branch locking interface, a branch display control interface, and/or a sub-branch display control interface. Optionally or alternatively, user interfaces may include: (a) a first section including plural items having a first common visual characteristic; and (b) a second section including plural items having a second common visual characteristic. In this manner, the common visual characteristics may indicate an association between the items sharing the characteristic.

Abstract: A method and system are provided for searching and finding help files and wizards of computer operating systems and computer software applications that allow system administrators or users to quickly find the help file or wizard, invoke the help file or wizard, and execute the help file or wizard. Search keywords may be entered into a search dialog using a variety of different languages.
