A motor vehicle traction battery module having a battery housing, in which multiple pouch battery cells are arranged. A plate-shaped cooling structure for direct cooling of the pouch battery cells by a cooling liquid is arranged between two adjacent pouch battery cells. The cooling structure which is compressible in the transverse direction (Y) and perpendicular to its plate plane (xz), includes a first studded plate having a constant plate thickness with a plurality of shaped hollow studs, whose stud peaks contact a side wall of an adjacent pouch battery cell; a second studded plate that is identically shaped to the first studded plate, so that the stud peaks of the second studded plate contact a side wall of the adjacent pouch battery cell; and an elastic pressure structure between the two studded plates, through which the two studded plates are pushed away from one another over their entire surface.
