STAMPED FUEL CELL BIPOLAR PLATE

摘要

A bipolar plate assembly (8) for a fuel cell (2) having a pair of stamped plates (100,200) joined together to define a coolant volume (300) therein. Each of the pair of stamped plates (100,200) have a flow field (102,202) arranged to maximize the contact area between the plates (100,200) while allowing coolant to distribute and flow readily within the coolant volume (300). The bipolar plate assembly (8) further includes a seal arrangement (26,28,30,32) and integral manifold to direct gaseous reactant flow through the fuel cell (2).
