Patent number: 9895967Abstract: A piping member that is used for a moving body equipped with a fuel cell and that is configured to suppress potential troubles caused by drainage water of the fuel cell. A fuel cell vehicle includes an exhaust pipe that is a piping member configured to discharge drainage water and exhaust gas of a fuel cell. The exhaust pipe includes an extended portion, a curved portion and an opening end portion and is mounted such that the exhaust pipe opens downward on the rear side of the fuel cell vehicle. The exhaust pipe is configured such that an inner wall surface of a wall portion of the opening end portion located on the front side of the vehicle is inclined from the rear side toward the front side of the fuel cell vehicle to be extended to an opening, in the state that the exhaust pipe is mounted to the fuel cell vehicle.Type: GrantFiled: October 3, 2014Date of Patent: February 20, 2018Assignee: Toyota Jidosha Kabushiki KaishaInventors: Ryota Akaboshi, Yasuki Otake, Shunichi Shibasaki, Yasuhiko Ohashi, Shigeyuki Terada

Patent number: 9261528Abstract: An impact detecting device includes a first impact detecting portion, a determining portion and an informing portion. The first impact detecting portion detects an impact applied to an object equipped to a vehicle. The determining portion determines that the object has received the impact when a detection result of the first impact detecting portion is greater than a first impact determination threshold. The informing portion informs that the object has received the impact, when the determining portion determines that the object has received the impact.Type: GrantFiled: March 24, 2014Date of Patent: February 16, 2016Assignees: DENSO CORPORATION, TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yasuo Imamura, Tateki Takayama, Yasuki Otake, Tomoaki Nakashima, Norihiko Nagae, Tsutomu Kondo, Yujiro Miyata

Patent number: 8865365Abstract: A connector is connected with a connector joint structure formed in separators in a fuel cell. The connector has: a connector casing; a terminal element that is provided in the connector casing and is configured to be in contact with an edge side of the separator and to be elastically deformed in an insertion direction of the connector that is orthogonal to a stacking direction of the separators, when the connector is connected with the connector joint structure; and an engagement element that is formed in the connector casing and is configured to engage with the connector joint structure and restrict motion of the connector in the insertion direction when the connector is connected with the connector joint structure.Type: GrantFiled: May 28, 2010Date of Patent: October 21, 2014Assignee: Toyota Jidosha Kabushiki KaishaInventors: Yasuki Otake, Hiroshi Fujita

Patent number: 7811715Abstract: An electrically conductive porous body for a fuel cell has a porous metal body and an electrically conductive layer that is disposed on one surface side of the porous metal body and that has gas permeability, wherein at least a part of the one surface side of the porous metal body is buried into one surface side of the electrically conductive layer, and wherein the flatness of the other surface side of the electrically conductive layer, into which the porous metal body is not buried, is higher than the flatness of the one surface side of the porous metal body. Sufficient contact surface area is obtained between the porous metal body and the membrane electrode assembly, without applying pressure to the porous metal body. It is therefore possible to achieve a low contact resistance with the membrane electrode assembly, without causing a change in the internal condition of the porous metal body.Type: GrantFiled: November 23, 2006Date of Patent: October 12, 2010Assignee: Toyota Jidosha Kabushiki KaishaInventor: Yasuki Otake

Publication number: 20100068570Abstract: A fuel cell system is provided which efficiently performs a scavenging process for a fuel cell stack (10) constituted of a plurality of fuel cells (40) each of which generates electric power using reaction gas supplied. When the power generation of the fuel cell stack (10) is stopped or when the power generation of the fuel stack (10) is not being performed, a scavenging process is performed in which the reaction gas, as a scavenging gas, is circulated from the gas passage portions (44, 46) to the outlet manifold (62, 68). During the scavenging process, the area via which the scavenging gas is discharged from each gas passage portion (44, 46) to the outlet manifold (62, 68) is limited, and the area to be limited is sequentially switched from one to another.Type: ApplicationFiled: April 10, 2008Publication date: March 18, 2010Inventor: Yasuki Otake
