<P>PROBLEM TO BE SOLVED: To provide piping for fuel cell which suppresses occurrence of voltage decrease due to impairment of discharge of water generated in a fuel cell during driving of a fuel cell vehicle. <P>SOLUTION: This is the piping for fuel cell 4 installed for fluid discharge on a fuel cell 1 for vehicle mounting having a structure equipped with a plurality of battery cell laminates. The plurality of cell laminates are arranged in front and rear direction of the vehicle with the lamination direction of the plurality of cells of the cell laminates being in vehicle width direction, and the piping 4 is a collected pipe to join at a confluence portion installed in the middle of the discharge route from each cell laminate, and is provided with a reverse-flow suppression part 5 to suppress reverse flow of fluid in the middle of the piping going to the confluence portion 4a. The reverse-flow suppression part 5 includes the confluence portion 4a which is, for example, shifted to the front direction or rear direction of the vehicle from the center position of the fuel cell 1. <P>COPYRIGHT: (C)2008,JPO&INPIT |
