Patent number: 7713056Abstract: A catalytic combustor is configured to accelerate the combustion processing of anode off gas in the combustor to reduce the amount of unburned hydrogen discharged to the outside of the combustor. Anode off gas and cathode off gas discharged from the fuel cell are fed into the catalytic combustor and combusted with a catalyst. Ventilation air is supplied from inside of the fuel cell is also supplied to the catalytic combustor. A portion of the catalytic combustor located upstream of the catalyst inside is divided into an upper flow path and a lower flow path by a partitioning plate and a gas flow passage is provided upstream of the upper and lower flow paths. The cathode off gas is supplied to the gas flow passage.Type: GrantFiled: June 29, 2006Date of Patent: May 11, 2010Assignee: Nissan Motor Co., Ltd.Inventors: Karuki Hamada, Tadashi Shoji, Nobuo Sakiyama

Publication number: 20090016401Abstract: An apparatus and method for determining a combustion state includes a catalytic combustion unit for mixing an anode off-gas discharged from a fuel pole of a fuel cell and an oxidizing agent gas, and having a catalytic unit for performing combustion processing. An upstream temperature detecting unit detects a gas temperature at an upstream side of the catalytic unit, and a gas-phase combustion determining unit compares at least one of the gas temperature detected by the upstream temperature detecting unit and a rate of upstream temperature increase with a determining reference value to determine if gas-phase combustion occurs at the upstream side of the catalytic unit.Type: ApplicationFiled: February 7, 2007Publication date: January 15, 2009Applicant: NISSAN MOTOR CO., LTD.Inventors: Karuki Hamada, Nobuo Sakiyama

Publication number: 20080118879Abstract: A controller determines whether a rate of temperature rise on an upstream side of a catalyst portion is at a determination criterion value or higher, and, when the rate of temperature rise on the upstream side of the catalyst portion is at the determination criterion value or higher, the controller determines that a combustor is in an abnormal combustion state. Therefore, an abnormal combustion state of the combustor can be detected before temperature of the combustor becomes high.Type: ApplicationFiled: November 1, 2005Publication date: May 22, 2008Inventors: Karuki Hamada, Tadashi Shoji, Nobuo Sakiyama

Publication number: 20050136302Abstract: A fuel cell generates electric power by the electrochemical reaction of hydrogen and the oxygen in air. After the hydrogen discharged without being consumed by an anode is burned in a burner, it is discharged out of a fuel cell system. Therefore, the fuel cell system has a cathode switch valve in the middle of the cathode line, and when the fuel cell system stops, non-saturated air of a compressor bypasses the fuel cell, and supplies the air to the catalytic burner. Although the cathode exhaust gas of saturated water vapor is circulating to the catalytic burner at the time of regular operation of the fuel cell, the non-saturated air which bypasses the fuel cell and is supplied can replace the inside of the catalytic burner with dry air. Therefore, the amount of water vapor in the catalytic burner is decreased at the time of a stop, and the catalyst is quickly activated at the time of re-starting.Type: ApplicationFiled: August 26, 2004Publication date: June 23, 2005Inventors: Tadashi Shoji, Karuki Hamada
