PROBLEM TO BE SOLVED: To provide a fuel battery module capable of excellently discharging water and suppressing occurrence of flooding even when cells are arranged vertically.SOLUTION: In a fuel battery module, plural gas flow paths 381 are arranged to extend in the longitudinal direction of a fuel battery cell 20, when one side 301 in the longitudinal direction of the fuel battery cell 20 is placed on the upper side in the direction of gravity while the other side 302 opposite to the one side 301 is placed on the lower side in the direction of gravity, a convex portion 392 for narrowing the flow path cross-sectional area of the gas flow path 381 is provided on the side surface 38a of the upper side in the direction of gravity in the gas flow path 381 while no convex portion 392 is provided on the side surface of the lower side in the direction of gravity in the gas flow path 381.SELECTED DRAWING: Figure 3 【課題】セルを縦向きに配置した場合であっても、良好に水を排出することができ、フラッディングの発生を抑制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は、ガス流路３８１が燃料電池セル２０の長手方向に複数延在して配置されており、燃料電池セル２０の長手方向の一辺３０１を重力方向上側に且つ当該一辺３０１と対向する他辺３０２を重力方向下側に配置したときに、ガス流路３８１における重力方向上側の側面３８ａに、ガス流路３８１の流路断面積を絞る凸部３９２が設けられ、ガス流路３８１における重力方向下側の側面には凸部３９２が設けられていないことを特徴とする。【選択図】図３
