Patent number: 8501356Abstract: An additive typified by tris(trimethylsilyl)phosphate, tris(trimethylsilyl)borate, and tetrakis(trimethylsiloxy)titanium (Chem. 3) are applied to a nonaqueous electrolyte containing a chain carbonate and/or a chain carboxylate as a main solvent (contained at a ratio of 70 volume % or higher). It is preferable that 0?a<30 is satisfied, in which “a” denotes the volume of a cyclic carbonate among carbonates having no carbon-carbon double bond in the entire volume, defined as 100, of the carbonates having no carbon-carbon double bond and chain carboxylates in a nonaqueous solvent contained in the nonaqueous electrolyte (0<a<30 in the case no chain carboxylate is contained).Type: GrantFiled: March 4, 2009Date of Patent: August 6, 2013Assignee: GS Yuasa International Ltd.Inventors: Kazusa Ohkubo, Koji Sukino, Shigeki Yamate, Suguru Kozono, Yoshihiro Katayama, Toshiyuki Nukuda

Patent number: 8501359Abstract: When stopping an operation of a fuel cell power plant, a controller (30) first stops fuel gas supply to an anode (2), then supplies a dry oxidant gas to a cathode (3) such that the output voltage of the fuel cell stack (1) decreases. The controller (30) then connects a secondary battery (31) to the fuel cell stack (1) so as to consume an output power generated by a reaction of the residual fuel gas in the anode (2). After this processing, the controller (30) replaces the residual fuel gas in the anode (2) with dry oxidant gas, then maintains the fuel cell stack (1) in a closed state, thereby preventing local cell formation in the anode due to mixing of the residual fuel gas with oxidant gas, and hence preventing corrosion of a catalyst layer of the cathode (3) due to local cell corrosion.Type: GrantFiled: June 28, 2006Date of Patent: August 6, 2013Assignee: Nissan Motor Co., Ltd.Inventors: Ryoichi Shimoi, Seiho Sugawara

Patent number: 8501360Abstract: It is possible to suppress over-discharge of an accumulator even when the accumulator is in charge-limited state in a fuel cell output control device. A vehicle drive control system including a fuel cell and an accumulator uses a control unit having: an FC output instruction value calculation module which calculates an output instruction value of a fuel cell according to a power required by a rotary machine; a regeneration limit judgment module which judges whether regeneration is limited for the rotary machine; a battery limit judgment module which judges whether charge of the accumulator is limited; and a required power correction module which corrects the required power of the fuel cell when the charge of the accumulator is limited and neither of the fuel cell or the rotary machine generates power, so as to limit discharge from the accumulator.Type: GrantFiled: October 6, 2008Date of Patent: August 6, 2013Assignee: Toyota Jidosha Kabushiki KaishaInventor: Atsushi Imai

Patent number: 8501366Abstract: A membrane electrode structure suitable for use in a membrane electrode assembly (MEA) that comprises membrane-affixed metal nanoparticles whose formation is controlled by a photochemical process that controls deposition of the metal nanoparticles using a photocatalyst integrated with a polymer electrolyte membrane, such as an ionomer membrane. Impregnation of the polymer membrane with the photocatalyst prior to metal deposition greatly reduces the required amount of metal precursor in the deposition reaction solution by restricting metal reduction substantially to the formation of metal nanoparticles affixed on or near the surface of the polymer membrane with minimal formation of metallic particles not directly associated with the membrane.Type: GrantFiled: June 18, 2009Date of Patent: August 6, 2013Assignee: Sandia CorporationInventors: Yujiang Song, John A.
