Abstract: To prevent a reduction in the performance of a unit cell due to a gas shortage in a cathode chamber. An electrochemical reaction unit includes a unit cell, a cathode-side member, and an anode-side member. The electrochemical reaction unit satisfies the following condition on at least one of supply and discharge sides of the cathode chamber. Condition: the distance between the midpoint between opposite end points of a cathode-side opening group including an opening of a cathode-side communication channel and the midpoint (specific point) between opposite end points of an anode-side supply opening group including an opening of an anode-side supply communication channel in a direction parallel to an inner circumferential surface of a cathode chamber hole is shorter than the distance between the centroid of a cathode-side gas channel hole and the specific point in the direction parallel to the inner circumferential surface of the cathode chamber hole.

Abstract: An electrochemical reaction unit including a unit cell, a cathode-side member, and an anode-side member. The sum La of the distance Lai between a virtual straight line representing a center position of the unit cell and the midpoint between opposite end points of a cathode-side supply opening group and the distance Lao between the virtual straight line and the midpoint between opposite end points of a cathode-side discharge opening group is smaller than the sum Lf of the distance Lfi between the virtual straight line and the midpoint between opposite end points of an anode-side supply opening group including an opening of an anode-side supply communication channel and the distance Lfo between the virtual straight line and the midpoint between opposite end points of an anode-side discharge opening group including an opening of an anode-side discharge communication channel.

Abstract: An electrochemical reaction cell stack includes an electrochemical reaction block including three or more electrochemical reaction units arranged in a first direction; a first heat-absorbing member which is disposed on one side of the electrochemical reaction block in the first direction and absorbs heat generated from the electrochemical reaction block; and a second heat-absorbing member which is disposed on the other side of the electrochemical reaction block in the first direction and absorbs heat generated from the electrochemical reaction block. An upstream electrochemical reaction unit is disposed between the first heat-absorbing member and the downstream electrochemical reaction unit disposed closest to the first heat-absorbing member, and an upstream electrochemical reaction unit is disposed between the second heat-absorbing member and the downstream electrochemical reaction unit disposed closest to the second heat-absorbing member.
