Abstract
A bipolar plate assembly for a fuel cell having a pair of stamped plates joined together to define a coolant volume therein. Each of the pair of stamped plates have a flow field arranged to maximize the contact area between the plates while allowing coolant to distribute and flow readily within the coolant volume. The bipolar plate assembly further includes a seal arrangement and integral manifold to direct gaseous reactant flow through the fuel cell.
