An electrochemical reaction single cell including an electrolyte layer containing Zr and at least one of Y, Sc, and Ca, an anode disposed on one side of the electrolyte layer, a cathode containing Sr and Co and disposed on the other side of the electrolyte layer, and an intermediate layer disposed between the electrolyte layer and the cathode. The electrochemical reaction single cell exhibits an interface contact ratio of 25.5% to 68.6%, wherein the interface contact ratio is the ratio of the sum of the lengths of portions containing neither SrZrOnor cavities of an interfacial surface of the intermediate layer on the electrolyte layer side to the total length of the interfacial surface. Also disclosed is an electrochemical reaction cell stack including a plurality of electrochemical reaction single cells, at least one of which is the above described electrochemical reaction single cell.
