<P>PROBLEM TO BE SOLVED: To improve the detection accuracy of a sensor attached to an off-gas passage through which an off-gas discharged from a fuel cell passes, and to reduce failures of the sensor such as inability to measure. <P>SOLUTION: Gas piping 10 for a fuel cell is joined to a fuel cell 21 and allows an off-gas discharged from the fuel cell 21 to pass therethrough. The gas piping 10 comprises: an off-gas passage 24 through which the off-gas passes; a flange 2 connected to an end 24a of the off-gas passage 24 and joined to the fuel cell 21; and a sensor attachment member 3 that communicates with the off-gas passage 24 and that is used for attaching a sensor for detecting the state of the off-gas. The sensor attachment member 3 is connected to the flange 2. <P>COPYRIGHT: (C)2007,JPO&INPIT |
