Abstract:
1. A bipolar plate assembly for use in a fuel cell stack, comprising: (a) at least one flow field layer defining a flow 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 side reactant and an anode side reactant; wherein the at least one flow field layer is made from a porous carbon material and the perimeter portion is impregnated with a polymer material; wherein the at least one porous carbon layer is joined to: (i) the at least one impermeable layer on a first side by a first adhesive material; and (ii) the flow field layer perimeter on a second side by a second adhesive material; and wherein the at least one flow field layer defines reactant inlet and outlet ports and reactant flow passageways for each of the cathode side reactant and the anode side reactant.
