A device for cooling battery cells of a traction battery which are arranged in at least two battery cell planes positioned one on top of the other. The device includes a first cooling plate which is arranged between a first battery cell plane and a second battery cell plane and is in thermal contact with the battery cells of the first and the second battery cell plane. Second cooling plates are arranged within the first and the second battery cell plane and are in thermal contact with multiple battery cells of the respective battery cell plane. A cooling fluid inlet is formed on a first side of the first cooling plate. A cooling fluid outlet is formed on a second side of the first cooling plate. The cooling fluid flows from the cooling fluid inlet into the first cooling plate on the first side of the first cooling plate.

A power storage device comprises: a power storage stack; an accommodation case that has a bottom wall portion and accommodates the power storage stack therein; and an adhesive layer that has thermal conductivity and fixes the power storage stack to the bottom wall portion. The bottom wall portion includes a receiving portion that has a receiving surface on which the power storage stack is received, a lower wall portion located at a position lower in level than the receiving surface, and a connecting portion that interconnects the receiving portion and the lower wall portion. The adhesive layer includes a portion disposed between the receiving surface and the power storage stack, and a protruding portion that protrudes from the receiving surface to the connecting portion.
