ABSTRACT:
A bipolar separator which is formed from a plate having opposing first and second surfaces which are compatible with fuel gas and an oxidant gas, respectively. The plate is formed with a central area, first and second opposing troughs extending from first and second opposing sides of the central area, and third and fourth opposing troughs extending from third and fourth opposing sides of the central area. In the regions of its third and fourth sides, the central area is bent over and around so that the third and fourth troughs face and are adjacent to the central area. The first surface of the separator defines the extent of a first surface of the central area and the extents of the inner surfaces of the troughs of the separator. Similarly, the second surface of the separator defines the extents of a second opposing surface of central area and the extents of the outer surfaces of the troughs.
