POSITIONING DEVICE, STACKING DEVICE AND STACKING METHOD FOR REPEATING COMPONENTS OF A CELL STACK FOR BATTERY OR FUEL CELLS

Devices and methods to be used in large-scale production of battery cells or fuel cells when forming cell stacks, including a positioning device for positioning the repeating components of the cell stack. The positioning device includes at least one vibrating jaw having a vibrating jaw contact surface, and a positioning jaw which is rigid in operation and is arranged lower than an upper region of the vibrating jaw and has a positioning jaw contact surface. In one embodiment, the jaws engage each other by complementary protrusion-recess features on the contact surfaces. Alternatively or additionally, the vibrating jaw is provided to move along an arcuate path during oscillation, a tangent of the arcuate path lying on the positioning jaw contact surface.
