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.

Abstract: An interconnector-electrochemical reaction unit cell composite body including an electrochemical reaction unit cell, and an interconnector which has a first through hole defining a fuel gas flow channel and which is disposed on the side toward an anode of the electrochemical reaction unit cell. The interconnector includes a coating forming a first surface of the interconnector opposite the anode. The coating includes a first coating and a second coating a having reduction resistance higher than that of the first coating. The first coating forms a first surface region which is a portion of the first surface of the interconnector and which is located away from the first through hole. The second coating forms a second surface region which is a portion of the first surface of the interconnector, which surrounds the first through hole, and which is located between the first coating and the first through hole.

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.
