A fuel cell vehicle includes a travel prohibition control unit. In the case where a lid sensor detects an open state of a lid, the travel prohibition control unit performs travel prohibition control to prohibit travel of the fuel cell vehicle. In the case where the number of shift control operations has reached a release number within release time, the travel prohibition control unit releases the travel prohibition control, and in the case where the number of shift control operations has not reached the release number within the release time, the travel prohibition control unit continues the travel prohibition control. The release number is two or more.

A distance-to-empty presentation apparatus of a fuel cell vehicle includes: a traveling speed acquisition unit configured to acquire a traveling speed of the fuel cell vehicle; a traveling distance acquisition unit configured to acquire a traveling distance of the fuel cell vehicle in a fuel filling period, the fuel filling period is a period from the time when the fuel is filled in the fuel cell vehicle previously to the time when the fuel is filled in the fuel cell vehicle this time; a fuel residual amount acquisition unit configured to acquire a fuel residual amount of the fuel cell vehicle; a fuel consumption amount acquisition unit configured to acquire a fuel consumption amount of the fuel cell vehicle; a fuel efficiency calculation unit configured to calculate fuel filling period fuel efficiency by using the traveling distance in the fuel filling period and a traveling period fuel consumption amount that is the fuel consumption amount during traveling preparation and during traveling in the fuel filling period, wherein the fuel filling period fuel efficiency is fuel efficiency in the fuel filling period; a distance-to-empty calculation unit configured to calculate a distance to empty of the fuel cell vehicle by using the fuel filling period fuel efficiency and the fuel residual amount; and a presentation device configured to present the distance to empty.

Provided is a gas detection device that includes a gas sensor, a power supply circuit that applies voltage to the gas sensor, and a control circuit that determines whether a leak of gas is present. The power supply circuit includes a reset power source that generates a first voltage, and a detection power source that generates a detection voltage for measuring resistance of a metal-oxide layer of the gas sensor. When a value of a current flowing through the metal-oxide layer is a predetermined value ITH or greater, the reset power source applies the first voltage to the gas sensor to perform a reset of resetting the metal-oxide layer of the gas sensor to a high-resistance state, and the control circuit determines that a leak of gas is present, depending on a state in which the reset is performed after the reset is performed for the first time.

A tank system for an aircraft, including a tank including an inner enclosure including a closed inner skin configured to store dihydrogen and an outer enclosure including an outer skin that surrounds the inner enclosure, a chassis including a front frame at a front end of the tank, and an attachment arrangement which attaches the outer skin of the outer enclosure to the front frame. A system of this kind makes it possible to react forces through the outer skin, thus reducing a complexity of the chassis.

A fuel cell module includes a case body containing a cell stack body formed by stacking a plurality of power generation cells. The case body includes a plurality of connectors for mounting the fuel cell module into a fuel cell vehicle. The plurality of connectors include a first connector group used for mounting the fuel cell module into a first fuel cell vehicle in a manner that a stacking direction of the fuel cell module is substantially aligned with a first direction, and a second connector group used for mounting the fuel cell module into a second fuel cell vehicle in a manner that the stacking direction of the fuel cell module is substantially aligned with a second direction. Some connectors are common to both the first connector group and the second connector group.
