Abstract: An electrochemical reaction unit including a single cell including an electrolyte layer containing solid oxide, and a cathode and an anode which face each other in a first direction with the electrolyte layer intervening therebetween; a current collector disposed on a cathode side of the single cell and having a protrusion protruding toward the cathode; an electrically conductive coat covering a surface of the current collector; and an electrically conductive bonding layer bonding the cathode and the protrusion covered with the coat. In all sections of the protrusion taken in parallel with the first direction, a corner portion of the protrusion covered with the coat is covered with the bonding layer.

Abstract: 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. In the electrochemical reaction single cell, an SrZrO3 integrated value calculated by a predetermined method is 600 to 10,300. Also disclosed is an electrochemical reaction cell stack including a plurality of electrochemical reaction single cells.
