An apparatus for forming a structural member includes a tool platform and a pressure platform that may be movable relative to one another between an open position and a closed position. The first valve metal flow field plate has a first cooling channel adapted to receive an aqueous coolant and to contact the aqueous coolant at a position that inhibits the formation of shunt currents when the fuel cell is incorporated in a fuel cell stack. Text blocks may be identified within each frame by partitioning the frame into one or more segments and recording the segments having a pixel of a sufficiently high contrast.
