  • Bipolar plate for fuel cell
    Patent number: 8097385
    Abstract: The present disclosure provides for a bipolar plate assembly for use in a fuel cell stack. The bipolar plate assembly includes: (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. The at least a first flow field layer is made from a porous carbon material and the perimeter portion is impregnated with a polymer material. The porous carbon layer is joined to: (i) the at least one impermeable layer on a first side by an adhesive material; and (ii) the flow field layer perimeter on a second side by a second adhesive material. The at least a first 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.
