Zusammenfassung:	To improve the performance of an electrochemical reaction single cell.SOLUTION: An electrochemical reaction single cell includes a power generation portion in which an electrolyte layer, an air electrode, and a fuel electrode are superimposed in a first direction which is a direction in which the air electrode and the fuel electrode face each other, and a non-power generation portion which is not included in the power generation portion. The non-power generation portion includes a fuel electrode non-power generation portion that is a part of the fuel electrode. The fuel electrode non-power generation portion has an exposed surface exposed from members other than the fuel electrode constituting a fuel cell single cell, and a groove in which the length of an inlet port opened to the exposed surface is five times or more as large as the width of the inlet port.SELECTED DRAWING: Figure 6 【課題】電気化学反応単セルの性能を向上させる。【解決手段】電気化学反応単セルは、空気極と燃料極との対向方向である第１の方向に電解質層と空気極と燃料極とが重なっている発電部と、発電部に含まれない非発電部とを有する。非発電部は、燃料極の一部である燃料極非発電部を含む。燃料極非発電部は、燃料電池単セルを構成する燃料極以外の部材から露出する露出表面を有し、燃料極非発電部に、露出表面に開口する入り口の長さが当該入り口の幅の５倍以上である溝が形成されている。【選択図】図６
