Abstract: A water detection device is provided for a power generation cell. The power generation cell has a reactant gas flow field (oxygen-containing gas flow field) configured to allow a reactant gas to flow along a membrane electrode assembly. The water detection device includes an electrically conductive member and a support member. The support member is an insulating member. The support member covers, and supports an electrically conductive member, and has an opening which exposes part of the electrically conductive member as an electrode. The opening is provided at a position facing a reactant gas flow field.

Abstract: An external environment recognition apparatus including: an in-vehicle detector configured to scan and emit an electromagnetic wave in a first direction and as a second direction to detect an external environment situation around a subject vehicle; and a microprocessor configured to acquire road surface information based on a detection data of the in-vehicle detector. The in-vehicle detector acquires a three-dimensional point cloud data frame by frame, and the microprocessor is configured to perform: recognizing a surface of the road and a three-dimensional object on the road for each frame as the road surface information based on the three-dimensional point cloud data, and determining an interval of detection points of the three-dimensional point cloud data of a next frame as a scanning angular resolution of the electromagnetic wave based on a size of a predetermined object and a distance from the subject vehicle to the object.

Abstract: A voltage applying unit of a water detecting device applies, to a pair of electrodes, a voltage changing within an application range that includes a first voltage which is smaller than an electrolysis voltage of water and a second voltage which is larger than the electrolysis voltage of the water. A judging unit judges presence or absence of the water based on change in electric current measured by a current measuring unit when the voltage changing within the application range is applied to the pair of electrodes.

Abstract: A method for manufacturing a carbon fiber sheet, the method including a carbon fiber forming step of heating a resin sheet to a carbonization temperature at a heating rate of 15,000° C./sec or higher, thereby forming a carbon fiber from the resin sheet. In the carbon fiber forming step, the resin sheet is preferably irradiated with an energy ray having an output density of 130 W/mm2 or higher and an amount of irradiation energy of 0.05 J/mm2 or more.
