A fuel cell system monitoring fuel gas detection results of a gas sensor after outputting a valve-opening command signal to a first on-off valve and outputting a valve-closing command signal to the second on-off valve when an operation of a fuel cell stack is stopped and an oxygen-containing gas stops flowing through oxygen-containing gas supply flow path.

Fuel cell system

A hydrogen sensor includes a communication terminal, a plurality of identification terminals, and an ID setting section. The communication terminal is connected to a first communication bus or a second communication bus, and communicate with a vehicle ECU. Each of the plurality of identification terminals is set to either an open state (OPEN) in which the identification terminal is not connected to any potential or a grounded state (GND) in which the identification terminal is connected to a ground potential. The ID setting section sets an identifier in either a standard format or an extended format, according to a difference in the communication bus to which the communication terminal is connected.

Sensor and sensor system

When leakage of fuel gas is detected by detection signals or disruption of the detection signals is detected, a FCECU limits a supply amount of the fuel gas from a fuel gas supply device, and shuts off the supply of the fuel gas by the fuel gas supply device when determining, after limiting the supply amount of the fuel gas, that the leakage of the fuel gas or the disruption of the detection signals has occurred.

A high pressure tank apparatus includes a high pressure tank, a leaked fluid container, and a supply/discharge side discharge flow path. The high pressure tank includes a liner made of resin, a reinforced layer that covers an outer surface of the liner, an insertion member that has formed therein a supply/discharge hole capable of communicating with an inside of the liner and the supply/discharge flow path; and a supply/discharge side cap in which are formed an insertion hole through which the insertion member is inserted and a supply/discharge side draw-out hole that draws out the fluid interposed between the liner and the reinforced layer. The supply/discharge side discharge flow path guides a temporarily released fluid that is the fluid drawn out via the supply/discharge side draw-out hole to a discharge region.
