Patent number: 9259727Abstract: A gas-reforming catalyst is modified to obtain stability in high temperature. The catalyst uses ?-Al2O3 as a carrier and is nano-porous. Hence, reaction surface is greatly broadened; and platinum contained inside does not become bigger after times of use. The catalyst does not deposit carbon and has long life. The stability of the catalyst can be still remained even at a temperature higher than 800° C.Type: GrantFiled: October 23, 2012Date of Patent: February 16, 2016Assignee: Institute of Nuclear Energy Research, Atomic Energy Council, Executive Yuan, R.O.C.Inventors: Ning-Yih Hsu, King-Tsai Jeng, Shean-Du Chiou, Su-Hsine Lin, Hwa-Yuan Tzeng, Wan-Min Huang, Yuan-Ming Chang, Ruey-Yi Lee

Patent number: 8273230Abstract: A cathode electrophoretic deposition (EPD) suspension is provided by mixing an ionomer solution with an electrolyte. An anode EPD suspension is provided via mixing carbon nanomaterial (CNM)-supported catalyst with a solution of the same composition as that of the cathode EPD suspension. Ultrasonication and high-speed stirring are executed on the cathode and anode EPD suspensions, thus turning them into homogenous suspensions. There is provided a low-voltage EPD apparatus incorporated with a porous material to separate it into anode and cathode compartments. The anode and cathode EPD suspensions are filled in the anode and cathode compartments, respectively. An inert gas is introduced into the anode compartment for stirring the anode EPD suspension. An electrode base substrate is used as the anode of the EPD apparatus. A low-voltage direct current (DC) power supply is used to supply DC low voltage to the EPD apparatus, thus evenly coating a catalyst layer on the substrate.Type: GrantFiled: February 15, 2008Date of Patent: September 25, 2012Assignee: Atomic Energy Council—Institute of Nuclear ResearchInventors: King-Tsai Jeng, Wan-Min Huang

Patent number: 7700520Abstract: This invention relates to the preparations of noble metal catalysts, i.e., platinum and platinum alloys, on suitable supports with nanonetwork structures and high catalytic efficiencies. A compact structure of a monolayer or a few layers is formed by self-assembly of organic polymer, e.g., polystyrene (PS), nanospheres or inorganic, i.e., silicon dioxide (SiO2), nanospheres on a support surface. In the void spaces of such a compact arrangement, catalyst is formed by filling with catalyst metal ion-containing aqueous solution and reduced by chemical reduction, or formed by vacuum sputtering. When using organic polymer nanospheres as the starting or structure-directing material, the polymer particles are removed by burning at a high temperature and the catalyst having a nanonetwork structure is obtained.Type: GrantFiled: April 22, 2005Date of Patent: April 20, 2010Assignee: Institute of Nuclear Energy ResearchInventors: Chun Ching Chien, King Tsai Jeng, Shean Du Chiou, Su Hsine Lin

Patent number: 6991869Abstract: A subassembly for a stack of electrochemical cells that includes a porous metal sheet having a first face and a second face with a hydrophobic, carbonaceous gas diffusion layer disposed within the pores along the first face of the porous metal sheet. The second face of the porous metal sheet defines a flow field while that portion of the porous metal sheet filled with the gas diffusion layer forms a current collector. The subassembly may further include a metal gas barrier metallurgically bonded to the second face of the porous metal sheet to act as a gas barrier between the porous metal sheet and a second porous metal sheet having a second gas diffusion layer disposed within the pores along a face of the second porous metal sheet. Preferably, the gas diffusion layers are applied as a paste to the porous metal sheet and then dried.Type: GrantFiled: October 17, 2002Date of Patent: January 31, 2006Assignee: Lynntech Power Systems, Ltd.Inventors: Alan J.

Publication number: 20030124411Abstract: The invention provides for reducing the number of parts and the number of interfaces found in certain types of chemical reactors, particularly in electrochemical reactors, and especially in the type or reactor known as a fuel cell or fuel cell stack. This reduction comes from the use of a unified structure that combines the functions normally carried out by several components in the unit, particularly by combining the functions of the gas distribution structure and the gas diffusion structure, the gas distribution structure and the gas barrier structure, or all three structures into a single, unitary, metallic part. This offers the advantages of simplified design, better performance, and lighter weight.Type: ApplicationFiled: October 17, 2002Publication date: July 3, 2003Applicant: Lynntech, Inc.Inventors: Alan J.

Patent number: 6426161Abstract: Thin, light weight bipolar plates for use in electrochemical cells are rapidly, and inexpensively manufactured in mass production by die casting, stamping or other well known methods for fabricating magnesium or aluminum parts. The use of a light metal, such as magnesium or aluminum minimizes weight and simultaneously improves both electrical and thermal conductivity compared to conventional carbon parts. For service in electrochemical cells these components must be protected from corrosion. This is accomplished by plating the surface of the light weight metal parts with a layer of denser, but more noble metal. The protective metal layer is deposited in one of several ways. One of these is deposition from an aqueous solution by either electroless means, electrolytic means, or a combination of the two. Another is deposition by electrolytic means from a non-aqueous solution, such as a molten salt.Type: GrantFiled: October 25, 2000Date of Patent: July 30, 2002Assignee: Lynntech, Inc.Inventors: Alan J.
