PROBLEM TO BE SOLVED: To provide a fuel manifold used in the stack structure of a fuel battery, the fuel manifold being designed such that even after the fuel battery is operated for a long time, an introduction pipe is firmly joined and fixed to the wall of the fuel manifold.SOLUTION: A fuel manifold body 200 performs the function of supplying fuel gas in the internal space to each fuel gas passage of a plurality of fuel battery cells. The fuel manifold body 200 is provided with an introduction pipe 230 for introducing fuel gas into the internal space. While one end part of the introduction pipe 230 is inserted into a through-hole formed in a support plate 220 (the upper wall of the fuel manifold), the one end part is welded to the support plate 220 on the internal space side. Thereby, the introduction pipe 230 is joined and fixed to the support plate 220.SELECTED DRAWING: Figure 9 |
