Patent number: 7622216Abstract: The durability of a fuel cell having a polymer electrolyte membrane with an anode on one surface and an oxygen-reducing cathode on the other surface is improved by substituting electrically conductive titanium carbide or titanium nitride particles for carbon particles as oxygen-reducing and hydrogen-oxidizing catalyst supports. For example nanosize platinum particles deposited on nanosize titanium carbide or titanium nitride support particles provide good oxygen reduction capability and are corrosion resistant in an acid environment. It is preferred that the catalyst-on-titanium carbide (nitride) particles be mixed with non-catalyst-bearing carbon in the electrode material for improved electrode performance.Type: GrantFiled: May 1, 2006Date of Patent: November 24, 2009Assignee: GM Global Technology Operations, Inc.Inventors: Ion C.

Patent number: 5139818Abstract: Photochemical and electroless metallization techniques have been combined to create high resolution circuits with line widths and spaces of about one mil on alumina substrates. In this process, small amounts of a xylene-soluble platinum metallo-organic compound are first applied to the surface of the alumina substrate. A mask is then used to selectively expose the platinum metallo-organic compound to ultraviolet light in the areas that are to be metallized, so as to transform the platinum metallo-organic compound into a xylene-insoluble form. After a xylene rinse removes the original soluble platinum compound from the unexposed areas, the substrate is fired in air at about 450.degree. C. for about five minutes, so as to pyrolize the insoluble, irradiated platinum metallo-organic compound into catalytically active platinum. This is followed by electroless deposition of copper onto the ultraviolet-treated regions where the catalytically active platinum resides.Type: GrantFiled: June 6, 1991Date of Patent: August 18, 1992Assignee: General Motors CorporationInventor: Andrew M.

Patent number: 4916115Abstract: Fine line superconductors of yttrium-barium-copper were formed on <100> strontium titanate substrates by the completely non-vacuum techniques of metallo-organic deposition in selective laser pyrolysis. Lines 125 micrometers wide were written in a film of metal neodecanoates, using an argon laser, prior to complete pyrolysis. An organic dye which absorbs selective laser light wavelengths, is added to the metallo-organic solution comprising the metal neodecanoates prior to laser exposure, so as to enhance absorption of the laser light at the regions of the metallo-organic film which are subsequently exposed to the laser light. The increased light absorbance at the exposed regions, results in at least partial pyrolysis of the exposed metal neodecanoates. Regions of the metallo-organic film not exposed to laser pyrolysis is developed away using a xylene wash.Type: GrantFiled: June 20, 1988Date of Patent: April 10, 1990Assignee: General Motors CorporationInventors: Joseph V.

Patent number: 4661372Abstract: A method is described for depositing an electroless copper plate onto a region of a styrene-derivative polymer surface using a vacuum deposited copper catalyst. Prior to depositing the catalyst, the region is treated with ultraviolet radiation while exposed to air. It is found that the vacuum-deposited copper is active to catalyze electroless deposition onto the treated region, but not upon a similar region not subjected to the ultraviolet treatment.Type: GrantFiled: December 23, 1985Date of Patent: April 28, 1987Assignee: General Motors CorporationInventor: Andrew M.
