<P>PROBLEM TO BE SOLVED: To ensure both corrosion proof property and pipe fixing property in a gas piping system for fuel cell. <P>SOLUTION: In a gas piping system for a fuel cell, a gas pipe 44 is made of stainless steel containing no nickel and is fixed at a room temperature with respect to a suspension member 50 or a fixing portion through a fixing tool 60 by means of bolts/nuts 53, 54, 55 and 56. The fixing tool 60 is constituted to include a bracket member and an elastic member 66, and this elastic member 66 is arranged between the bracket member and the gas pipe 44. Moreover, the fixing tool 60 is equipped with such a notched portion 70 that the fixing tool 60 may be self-ruptured when an excessive external force is applied to a fuel cell stack 12 constituting a fuel cell system. <P>COPYRIGHT: (C)2008,JPO&INPIT |
