Zusammenfassung:PROBLEM TO BE SOLVED: To provide a fuel cell capable of equalizing power generation reaction in the whole cell body.SOLUTION: An inter-connector 3 of a fuel cell 1 has a fuel passage formation section 13 for forming a fuel passage 15 in which a fuel to be supplied to a fuel electrode of a cell body flows and an air passage formation section 14 for forming an air passage 16 in which air to be supplied to an air electrode of the cell body flows. A direction in which the fuel is allowed to flow in the fuel passage 15 and a direction in which air is allowed to flow in the air passage 16 are intersected with each other. The fuel passage formation section 13 has projections 19A-19C arranged so that pressure loss of the fuel in an area corresponding to an upstream side area of the air passage 16 is larger than pressure loss of the fuel in an area corresponding to a downstream side area of the air passage 16. The air passage formation section 14 has projections 20A-20C arranged so that pressure loss of air in an area corresponding to an upstream side area of the fuel passage 15 is larger than the pressure loss of air in an area corresponding to a downstream side area of the fuel passage 15.SELECTED DRAWING: Figure 3 【課題】セル本体における発電反応の均一化を図ることができる燃料電池を提供する。【解決手段】燃料電池1のインターコネクタ3は、セル本体の燃料極に供給される燃料が流れる燃料流路15を形成する燃料流路形成部13と、セル本体の空気極に供給される空気が流れる空気流路16を形成する空気流路形成部14とを有し、燃料が燃料流路15を流れる方向と空気が空気流路16を流れる方向とは交差しており、燃料流路形成部13は、空気流路16の上流側の領域に対応する領域における燃料の圧力損失が空気流路16の下流側の領域に対応する領域における燃料の圧力損失よりも大きくなるように配置された突起19A〜19Cを有し、空気流路形成部14は、燃料流路15の上流側の領域に対応する領域における空気の圧力損失が燃料流路15の下流側の領域に対応する領域における空気の圧力損失よりも大きくなるように配置された突起20A〜20Cを有する。【選択図】図3
