  • Patent number: 8216982
    Abstract: Disclosed is a low-phosphorous lubricant produced by a process comprising forming a lubricant additive by reacting metal halide and organophosphate together to form a reaction mixture, the metal halide participating as a reactant, and adding at least a portion of the reaction mixture to a lubricant base comprising from about 0.01 weight percent phosphorous to about 0.1 weight percent phosphorous.
    Type: Grant

  • Patent number: 8216986
    Abstract: A lubricant additive produced by the process comprising mixing a metal halide with an organophosphate, the metal halide participating as a reactant and reacting the metal halide and the organophosphate to produce a reaction mixture comprising the lubricant additive. Also disclosed is a lubricant produced by the process comprising forming a lubricant additive by reacting metal halide and organophosphate together to form a reaction mixture, the metal halide participating as a reactant, and adding at least a portion of the reaction mixture to a lubricant base.

  • Publication number: 20090087549
    Abstract: A method is provided for selectively coating a catalyst layer (158) on an electrode of a fuel cell. A porous conductive material (154) comprising gold is formed overlying a portion of a dielectric material (114) to form the electrode. The porous conductive material (154) and the dielectric material (114) are coated with the catalyst layer (158) comprising a carbon supported platinum. The catalyst layer (158) is washed with a solvent to substantially remove the catalyst layer (158) from the dielectric material (114). Optionally, an ionomer component is diffused into the catalyst layer (158) remaining on the porous conductive material (154). The catalyst coated (158) circular channels (156) are then filled with an electrolyte layer (162).

  • Publication number: 20080182012
    Abstract: A method is provided for fabricating a hybrid gas diffusion layer/current collector/electrocatalyst structure (28) suitable for 3D microfuel cell devices (180). The method comprises forming a macroporous electrically conductive structure (28) on a substrate (12, 112) positioned such that a plurality of cathode current collector/GDL (168) and anode current collector/GDL (166) are formed. An electrocatalyst material (158) is deposited in contact with these structures, completing the formation of cathode (168) and anode (166) hybrid current collector/GDL/electrocatalyst structures. When electrolyte (158) is positioned between the electrocatalyst material (158) contacting the cathode collector (168) and the electrocatalyst material (158) contacting each of the plurality of anode collectors (166), the resulting MEA is suitable for use in a micro fuel cell device.
