BUS BAR ASSEMBLY FOR AN ELECTROCHEMICAL CELL STACK

摘要

An electrochemical cell stack assembly is disclosed comprising a member m ade 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 b ar to distribute compression forces over an interface area between the bus b ar and an insulator end plate, thereby reducing shear stresses in the starte r 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.
