Patent number: 9252444Abstract: A fuel cell system calculates amount of fluid discharged from a fuel gas circulation path with water and fuel gas in accordance with an ordinary process map if inside an anode is not scavenged when a fuel cell stops electrochemical reaction; measures amount of water remaining in a fuel gas circulation path in accordance with cumulative electricity output, temperature, or elapsed time after starting the electrochemical reaction if the inside the anode is scavenged previously; and determines whether the inside the fuel gas circulation path is in dry condition or humid condition. The fuel cell system calculates amount of fluid discharged from the fuel gas circulation path with water or the fuel gas in accordance with a map predetermined for the dry condition if the fuel cell system determines that the inside the fuel gas circulation path is in the dry condition.Type: GrantFiled: September 2, 2009Date of Patent: February 2, 2016Assignee: HONDA MOTOR CO., LTDInventors: Koichiro Miyata, Kentaro Nagoshi, Junji Uehara, Yuji Matsumoto

Patent number: 9093679Abstract: A method of shutting down a fuel cell system includes a first step of supplying hydrogen gas and air to a fuel cell stack to thereby cause the fuel cell stack to generate electricity, and a second step of stopping supply of the hydrogen gas, and then supplying air to the fuel cell stack so as to cause the fuel cell stack to generate electricity upon detection of a command to shut down the fuel cell stack. In the second step, when the pressure of the hydrogen gas is lowered to a preset lower-limit value based on an anode pressure, which actually is measured, the fuel cell stack is caused to stop generating electricity.Type: GrantFiled: September 20, 2011Date of Patent: July 28, 2015Assignee: HONDA MOTOR CO., LTD.Inventors: Shinjiro Morita, Nobutaka Nakajima, Go Kikuchi, Nobuki Koiwa, Satoshi Tanimoto, Kentaro Nagoshi, Katsumi Hayashi, Koichiro Miyata, Hiroshi Morikawa, Kaoru Yamazaki, Takashi Yamamoto, Shinya Watanabe

Patent number: 8815458Abstract: A fuel cell system for a vehicle includes a fuel cell, a fuel supply device, an oxidizer supply device, an anode potential measuring device, and a discharge controller. The anode potential measuring device is configured to measure an anode potential of an anode. The discharge controller is configured to control discharge of electric current from the fuel cell as part of a process of stopping the fuel cell during idling of the vehicle. When receiving idle stop permission for the fuel cell, the discharge controller determines whether the fuel cell is permitted to discharge. When the anode potential is equal to or lower than a predetermined threshold value, the discharge controller permits the fuel cell to discharge. When the anode potential is higher than the predetermined threshold value, the discharge controller does not permit the fuel cell to discharge.Type: GrantFiled: March 16, 2011Date of Patent: August 26, 2014Assignee: Honda Motor Co., Ltd.Inventors: Koichiro Furusawa, Kentaro Nagoshi

Patent number: 8778553Abstract: A fuel cell includes a membrane electrode assembly and an anode side metal separator and a cathode side metal separator sandwiching the membrane electrode assembly. An oxygen-containing gas flows in an oxygen-containing gas flow field in a horizontal direction. A coolant flows in a coolant flow field in a vertical direction. The coolant flow field is connected to coolant supply passages and coolant discharge passages. The opening of one of the coolant supply passages and the opening of one of the coolant discharge passages are smaller than those of the other coolant supply passages and the other coolant discharge passages in cross section, respectively. Thus, the flow rate of the coolant supplied to an area near outlets of the oxygen-containing gas flow field and the fuel gas flow field become smaller than the flow rate of the coolant supplied to the other area.Type: GrantFiled: March 17, 2006Date of Patent: July 15, 2014Assignee: Honda Motor Co., Ltd.Inventors: Masahiro Mohri, Kentaro Nagoshi, Masaru Oda
