Abstract

See full text

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.
