Abstract
An electrochemical cell stack assembly is disclosed comprising a member made of an elastic and electrically conductive material placed between a bus bar and a starter plate. The elastic, electrically conducting member covers at least a peripheral region along a perimeter of a recess housing the bus bar to distribute compression forces over an interface area between the bus bar and an insulator end plate, thereby reducing shear stresses in the starter plate when the stack is compressed. An elastic pad also may be arranged in the recess and between the insulator end plate and the bus bar.
