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.
