Abstract

A bipolar plate () for use in a fuel cell stack () includes one or more first metal layers () having a tendency to grow an electrically passive layer in the presence of a fuel cell reactant gas and one or more second metal layers () directly adjacent the one or more first metal layers (). The second metal layer has a tendency to resist growing any oxide layer in the presence of the fuel cell reactant gas to maintain a threshold electrical conductivity. The second metal layer also has a section for contacting an electrode () and providing an electrically conductive path between the electrode () and the first metal layer.
