PROBLEM TO BE SOLVED: To provide a fuel cell module with improved performance for supplying gas to an electrode.SOLUTION: A passage forming body 10 used in a fuel cell module according to the present invention includes: a gas passage 120 for supplying gas to a fuel cell; a water guide passage 110 for discharging generated water from the fuel cell; and a connection passage 130 for connecting the gas passage 120 to the water guide passage 110. When viewing a protrusion 11 from a cross section perpendicular to a passage direction W, one of both ends of the outer shape of the protrusion 11 is formed to be located closer to the center side of the protrusion than a virtual surface 210 on which the passages are assumed to be linear along the passage direction W. When viewing the protrusion 11 in the passage direction W, a portion located on the center side of the protrusion is formed to be on the end of the outer shape of the protrusion on the opposite side in the right-left direction across the connection passage 130.SELECTED DRAWING: Figure 2 【課題】電極へのガス供給性を向上することができる燃料電池モジュールを提供する。【解決手段】本発明に係る燃料電池モジュールに用いられる流路形成体１０は、燃料電池にガスを供給するガス流路１２０と、燃料電池から生じた生成水を排水する導水路１１０と、ガス流路１２０と導水路１１０とを連通する連通路１３０と、を有し、凸部１１を流路方向Ｗに対して垂直な断面でみたときに、凸部１１外形の両端部の一方は、流路方向Ｗに沿って流路が直線形状と仮定した仮想面２１０よりも凸部中央側に位置するように形成されており、該凸部中央側に位置する部分は、凸部１１を流路方向Ｗにみたときに、連通路１３０を挟んで左右反対側の凸部外形の端部に形成されている。【選択図】図２
