Zusammenfassung:The fuel cell system includes a fuel cell stack and a predetermined device. A gas receiving portion for receiving an exhaust gas from the fuel cell stack is formed in the predetermined device. The gas outlets of the fuel cell stack and the gas receiving portion are connected via a pipe. An upstream portion of a joint tube made of an insulator is inserted into a downstream opening of the pipe. The joint tube has a hollow protrusion with a smaller outer diameter than the upstream portion. The hollow protrusion protrudes upstream (inside the pipe) from the upstream portion in the flow direction of the exhaust gas.
