Embodiments of the invention generally provide a method and wordline driver having a reduced leakage current. The rear lens group has a first lens unit having a positive refracting power, a second lens unit having a negative refracting power, and a third lens unit having a positive refracting power. The grasping tip includes a body housing at least one suction element, wherein the at least one suction element mechanically produces suction locally within the grasping tip. The fuel cell component may be assembled as part of a repeating unit for a fuel cell stack.
