Abstract:
1. A device for use in a fuel cell stack, comprising: a bipolar plate having at least one first metal layer that is solid and continuous, the at least one first metal layer including a cathode side and an anode side that each include reactant gas channels, and having a first oxide layer with a first growth rate in the presence of a fuel cell reactant gas; and a plurality of second metal layers, with one of the plurality of second metal layers being directly adjacent to the anode side and another of the plurality of second metal layers being directly adjacent the cathode side, each of the plurality of second metal layers comprising a mesh having a second oxide layer with a second growth rate less than the first growth rate in the presence of the fuel cell reactant gas such that the second oxide layer maintains a selected electrical conductivity, each of the plurality of second metal layers being directly bonded to the at least one first metal layer for providing an electrically conductive path between an electrode and the at least one first metal layer.
