FORMED PLATE ASSEMBLY FOR PEM FUEL CELL

摘要

A bipolar plate assembly for a fuel cell is provided. The bipolar plate assembly includes a cathode plate disposed adjacent an anode plate, the cathode and anode plates formed having a first thickness of a low contact resistance, high corrosion resistance material by a vapor deposition process. The first and second unipolar plates are formed on a removable substrate, and a first perimeter of the first unipolar plate is welded to a second perimeter of the second unipolar plate to form a hermetically sealed coolant flow path. A method for forming the bipolar plate assembly is also described.
