摘要：The present disclosure provides for a bipolar plate assembly for use in a fuelcell stack. The bipolar plate assembly includes: (a) at least one flow field layer defining aflow field portion and a perimeter portion; (b) at least one core assembly including at

least one porous carbon layer and at least one impermeable layer; and (c) a cathode sidereactant and an anode side reactant. The at least a first flow field layer is made from aporous carbon material and the perimeter portion is impregnated with a polymermaterial. The porous carbon layer is joined to: (i) the at least one impermeable layer on afirst side by an adhesive material; and (ii) the flow field layer perimeter on a second sideby a second adhesive material. The at least a first flow field layer defines reactant inletand outlet ports and reactant flow passageways for each of the cathode side reactantand the anode side reactant. A method of making such a bipolar plate as describedherein is also provided, as well as a method for rendering a layer of carbon materialsubstantially impervious to a liquid agent such as an acid and rendering the porouscarbon components wettable to retain an acidic liquid electrolyte. Fuel cell bipolar platesmade in accordance with the teachings herein exhibit excellent heat transfer

characteristics, and are particularly effective in conducting heat to the edge of a fuel cellstack.
