Gas piping system for fuel cell

摘要

There is provided a gas piping system for a fuel cell in which a gas pipe is made of stainless steel containing no nickel and is fixed at normal room temperature to a suspension member or a fixing portion through a fixing tool by means of bolts/nuts. The fixing tool is constituted to include a bracket member and an elastic member, and this elastic member is arranged between the bracket member and the gas pipe. Moreover, the fixing tool is equipped with a notched portion such that the fixing tool may be self-ruptured when an excessive external force is applied to a fuel cell stack constituting a fuel cell system.
