ELECTROCHEMICAL CELL STACK, FUEL CELL AND HYDROGEN MANUFACTURING DEVICE

To provide an electrochemical cell stack capable of reducing eccentricity of a fuel gas or air supplied to each of cells without changing an installation area, a fuel cell and an electrolysis device.SOLUTION: An electrochemical cell stack comprises: a laminate in which cells and separators are alternately laminated and in which a side face of the cell is enclosed by the separator; a manifold disposed on an end face of the laminate and including a fuel introduction part for introducing a fuel gas from the outside and an air introduction part for introducing air from the outside; a fuel supply channel which is a channel for the fuel gas to be supplied to the cells and extends from the fuel introduction part through the separators in a lamination direction of the separators; and an air supply channel which is a channel for the air to be supplied to the cells and extends from the air introduction parts through the separators in a lamination direction of the separators. The cells form multiple cell groups in its lamination direction and at least any one of the fuel supply channel and the air supply channel is provided for each of the cell groups.SELECTED DRAWING: Figure 2 【課題】設置面積を変えずに各セルへ供給される燃料ガスや空気の偏りを小さくできる電気化学セルスタック、燃料電池および電気分解装置を提供すること。【解決手段】本発明の実施形態によれば、セルとセパレータとが交互に積層されると共に、セルの側面がセパレータに囲われた積層体と、積層体の端面に配置され、外部から燃料ガスを導入する燃料導入部および外部から空気を導入する空気導入部をそれぞれ具備するマニホールドと、セルに供給される燃料ガスの流路であって、燃料導入部からセパレータを貫き、その積層方向に延びた燃料供給流路と、セルに供給される空気の流路であって、空気導入部からセパレータを貫き、その積層方向に延びた空気供給流路と、を備え、セルは、その積層方向に複数のセル群を形成し、燃料供給流路および空気供給流路の少なくともいずれかは、セル群ごとにそれぞれ設けられる。【選択図】図２
