<P>PROBLEM TO BE SOLVED: To provide a fuel cell system capable of preventing a film from stretching at a lower end of a pressure transmitting tube and capable of superbly detecting pressure of reaction gas. <P>SOLUTION: The fuel cell system 1 is provided with a fuel cell stack 10 generating power with reaction gas supplied, reaction gas supply means 21 and 31 supplying reaction gas to the fuel cell stack 10, a humidifier 32 humidifying reaction gas directed from the reaction gas supply means 21 and 31 toward the fuel cell stack 10, a pressure sensor 33 equipped with a pressure receiving part 33a for detecting pressure of reaction gas directed toward the fuel cell stack 10. The pressure sensor 33 is provided with a pressure transmitting tube 33b hung down from the pressure sensor 33 and equipped with an opening 33c at a lower end part A for transmitting pressure to the pressure receiving part 33a, and at least a part of the pressure transmitting tube 33b is arranged under environments of humidifying reaction gas humidified by the humidifier 32, and is equipped with a pointed part 33d at the lower end part A where waterdrops gather by their own weight. <P>COPYRIGHT: (C)2010,JPO&INPIT |
