<P>PROBLEM TO BE SOLVED: To provide an exhaust gas tube for a fuel cell that is low-cost, superior in elasticity, light-weight and rigid, and is capable of being fitted readily and surely into a body. <P>SOLUTION: The exhaust gas tube 1 is formed of resin, at least partly equipped with a bellows part 2, with a plate thickness of resin at the bellows part made into a thickness sufficient to withstand breakage at a trough part and a hill part by bending, and in the thinnest thickness manufacturable in a bellows shape; the valley part at 0.5 to 0.6 mm and the crest part at 0.1 to 0.3 mm, the plate thickness of the trough part formed larger than that of the crest part; and further, the dimensions and the angle of each part of the figure are set as: H:4.5 mm, P:3.3 mm, R1:0.5 mm, R2:0.2 mm, and θ:28°. <P>COPYRIGHT: (C)2009,JPO&INPIT |
