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.

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.

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.

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.
