Patent number: 7754368Abstract: A simple, inexpensive and highly efficient fuel cell has boundary structures made of a photo-sensitive material in combination with selective patterning. Printed circuit board (PCB) fabrication techniques combine boundary structures with two and three dimensional electrical flow path. Photo-sensitive material and PCB fabrication techniques are alternately or combined utilized for making micro-channel structures or micro stitch structures for substantially reducing dead zones of the diffusion layer while keeping fluid flow resistance to a minimum. The fuel cell assembly is free of mechanical clamping elements. Adhesives that may be conductively contaminated and/or fiber-reinforced provide mechanical and eventual electrical connections, and sealing within the assembly. Mechanically supporting backing layers are pre-fabricated with a natural bend defined in combination with the backing layers' elasticity to eliminate massive support plates and assist the adhesive bonding.Type: GrantFiled: December 19, 2007Date of Patent: July 13, 2010Assignees: The Board of Trustees of the Leland Stanford Junior, Honda Motor Co., LtdInventors: Jun Sasahara, Daniel Braithwaite, Suk-Won Cha, Tibor Fabian, Tadahiro Kubota, Nariaki Kuriyama, Sang-Joon John Lee, Ryan O'Hayre, Friedrich B.

Patent number: 7273671Abstract: In a fuel cell comprising a tubular casing, an electrolyte layer received in the tubular casing, and a pair of gas diffusion electrodes interposing the electrolyte layer and defining a fuel gas passage and an oxidizing gas passage, respectively, each gas diffusion electrode is formed by stacking a plurality of layers of material therefor, for instance in the axial direction of the casing. Because the gas diffusion layers are formed layer by layer, components can be formed in highly fine patterns so that a highly compact tubular fuel cell can be achieved. Similarly, the dimensions of the various elements of the fuel cell can be controlled in a highly accurate manner. Also, the geometric arrangement can be changed at will in intermediate parts of each gas passage.Type: GrantFiled: May 8, 2001Date of Patent: September 25, 2007Assignees: Honda Giken Kogyo Kabushiki Kaisha, Stanford UniversityInventors: Yuji Saito, Jun Sasahara, Nariaki Kuriyama, Tadahiro Kubota, Toshifumi Suzuki, Yuji Isogai, Friedrich B.

Patent number: 7253409Abstract: The present invention provides nano-patterning based on flow of an ion current within an ionic conductor to bring ions in proximity to a microscope probe tip touching a surface of the conductor. These ions are then electrochemically reduced to form one or more features on the surface. Ion current flow and the electrochemical reaction are driven by an electrical potential difference between the tip and the ionic conductor. Such features can be erased by reversing the polarity of the potential difference. Indentations can be formed by mechanically removing features formed as described above. The ions in the ion current can be provided by the ionic conductor and/or by oxidation at a counter electrode.Type: GrantFiled: July 20, 2005Date of Patent: August 7, 2007Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Minhwan Lee, Ryan O′Hayre, Turgut M. Gur, Friedrich B. Prinz

Patent number: 7195833Abstract: Dislocations are fabricated into electrolyte membrane films to increase ion conductivity. Ion and/or electron irradiation causes the growth of vacancy clusters within the thin film and collapsing into Frank dislocation loops that exhibit high ion conductivity. Maximum ion conductivity is accomplished by spatially reorienting the Frank dislocation loops during a following heat-treatment of the membrane. Thereby the dislocation loops form surface-to-surface continuous dislocations along which ions may propagate between membrane surfaces with minimal activation energies. Dislocation densities in the range of 108˜1014 cm/cm3 may be fabricated with conventional irradiation techniques into ceramics such as, for example yttria stabilized zirconia and doped ceria.Type: GrantFiled: May 29, 2003Date of Patent: March 27, 2007Assignees: The Board of Trustees of the Leland Stanford Junior University, Honda Giken Kogyo Kabushiki KaishaInventors: Yuji Saito, Friedrich B.
