Patent number: 8323841Abstract: A system and method for controlling the bleed valve in an anode recirculation loop of a fuel cell system. The system uses a model to determine the concentration of hydrogen in the recirculated gas by calculating the volume flow of the recirculated gas through a fuel cell stack, a pressure drop across the anode inlet and outlet of the stack, and the density of the recirculated gas, and using a measured temperature of the recirculated gas and a measured pressure drop across a recirculation pump.Type: GrantFiled: May 6, 2008Date of Patent: December 4, 2012Assignee: GM Global Technology Operations LLCInventors: Bernhard Baaser, Volker Formanski

Patent number: 8298720Abstract: A proton conductor is formed of a porous body as a substrate and proton-conducting polymer covalently bonded to inner surfaces of pores of the porous body. The proton-conducting polymer comprises a main chain and a plurality of branched side chains extending radially therefrom. The branched side chains are each bonded to a proton-conducting salt at the end. The proton-conducting polymer has a substantially cylindrical structure in which the salts can be circumscribed by a virtual circle having a center on the cross-sectional center of the main chain such that a radial direction of the virtual circle is perpendicular to a longitudinal direction of the main chain. The salts are located on the peripheral wall of the substantially cylindrical structure. Protons are transferred between the adjacent salts, so that a conduction channel is formed on the peripheral wall of the cylindrical structure.Type: GrantFiled: March 21, 2008Date of Patent: October 30, 2012Assignee: Honda Motor Co. Ltd.Inventors: Tadahiro Shiba, Hitoshi Iwadate

Patent number: 8168341Abstract: A fuel cell includes a plurality of electrolyte electrode assemblies and a pair of separators sandwiching the electrolyte electrode assemblies. A fuel gas supply channel formed by a channel member fixed to the separator is connected to a fuel gas inlet formed in an inner end of a trapezoidal section. Unburned hydrogen in an exhaust fuel gas consumed in the reaction at the anode, and discharged from the fuel gas channel to an oxygen -containing gas supply unit, is mixed with an oxygen-containing gas before consumption, burned, and then supplied to an oxygen-containing gas channel.Type: GrantFiled: May 15, 2006Date of Patent: May 1, 2012Assignee: Honda Motor Co., Ltd.Inventor: Hiroki Homma

Patent number: 8148031Abstract: A proton conductor system includes a solid oxide having at least one hydrogen vibrational mode defined by a bandwidth and resonance frequency. A light source irradiates the solid oxide with infrared light in a wavelength band having a center frequency matching the resonance frequency.Type: GrantFiled: November 12, 2009Date of Patent: April 3, 2012Assignee: College of William and MaryInventors: Gunter Luepke, Erik J. Spahr

Patent number: 8088520Abstract: The power supply apparatus includes a power supply unit, a piezoelectric element for transferring heat of the power supply unit to a floor panel, and an element power supply control circuit for controlling application of a voltage to the piezoelectric element. The piezoelectric element is placed between the power supply unit and the floor panel and is switched between a contact state in which the piezoelectric element is in contact with the power supply unit and the floor panel and a non-contact state in which the piezoelectric element is not in contact with the power supply unit and/or the floor panel in accordance with the application of a voltage.Type: GrantFiled: November 8, 2007Date of Patent: January 3, 2012Assignee: Toyota Jidosha Kabushiki KaishaInventor: Izumi Takahashi
