A battery of electrochemical cells employing several identical housing sections of conductive material stacked in a series arrangement with insulation between them at the points of connection. Each two adjacent housing sections form an enclosed chamber. Each chamber contains the electrochemical system of an electrochemical cell with the anode members in contact with one of the housing sections forming the chamber and the cathode members in contact with the other of the housing sections forming the chamber. The electrochemical cells within each chamber form a battery of cells arranged in series both physically and electrically with each housing section serving as the positive terminal for the cell of one chamber and the negative terminal for the cell of an adjacent chamber.
