STAMPED FUEL CELL BIPOLAR PLATE

摘要

An electro-conductive plate assembly for a fuel cell has a pair of stamped plates joined together to define a coolant volume therein. Each of the pair of stamped plates has a flow field on a major outer surface arranged to maximize the contact area between major inner surfaces of the plates while allowing coolant to distribute and flow readily within the coolant volume. The flow fields formed on the major outer surfaces provide corresponding sets of lands on the major inner surfaces that contact to form a third flow field of the coolant volume. The third flow field formed by the lands includes a plurality of longitudinal channels and an array of flow disruptors. The bipolar plate assembly further includes a seal arrangement and integral manifolds to direct reactant gas and coolant flow through the fuel cell.
