Abstract: An electrochemical reaction unit includes a unit cell including an electrolyte layer, and a cathode and an anode which face each other in a first direction with the electrolyte layer intervening therebetween, and one or a plurality of structural members. The electrochemical reaction unit further includes a glass seal member which contains glass and is in contact with two members facing each other in the first direction, the two members being selected from the unit cell and the one or the plurality of structural members. The glass seal member contains a plurality of crystal grains each having a ratio of a vertical dimension in the first direction to a horizontal dimension in a second direction orthogonal to the first direction of 1.5 or more.

Abstract: An electrochemical reaction unit containing 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 at least one section of the protrusion taken in parallel with the first direction, the protrusion covered with the coat has a covered portion covered with the bonding layer and an exposed portion exposed from the bonding layer and including a corner portion of the protrusion covered with the coat.

Abstract: An object is to effectively restrain Cr diffusion from a corner portion of a protrusion of a cathode-side current collector. The electrochemical reaction unit includes 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 unit which includes a unit cell including an electrolyte layer, a cathode, and an anode facing each other in a first direction; a current collector disposed on a cathode side of the unit cell; and an electrically conductive porous bonding layer. A bonding region contains a block portion and an electrical conductivity securing portion. The block portion has a pore having a diameter that is 20% or more than the thickness of the bonding region in the first direction. The block portion extends inward from one of opposite ends in a second direction orthogonal to the first direction of the bonding region, and reaches and contains the pore satisfying the pore requirement. The electrical conductivity securing portion is located toward the other end of the bonding region and has a smaller average diameter of pores than the block portion.
