NOVELTY - Stainless steel bipolar plate (170) for fuel cell comprises opposing surfaces which has flow channels (172) and lands (174) interspersed with flow channels, where the lands form electrically-conductive contact with fuel cell diffusion layer comprising nickel-based alloy to reduce electrical contact resistance between bipolar plate and diffusion layers (50, 60).    USE - In fuel cell to reduce electrical contact resistance between the plate and diffusion layer.    ADVANTAGE - The electrically-conductive contact is made up of nickel-based alloy that has roughness which can help to reduce contact resistance between plate and diffusion layer and improves electric current density. The nickel-chrome based material can be used to form substantial entirety of bipolar plate, thus no separate coating is necessary and also reducing manufacturing costs. The nickel-based alloys, iron-chromium alloys have higher corrosion resistance than iron-nickel substrate materials. The binary alloys yield good contact resistance without having to resort to surface texturing. With regard to manufacturability, all the alloys exhibit good weldability and formability.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) device having polymer electrode membrane fuel cell comprising membrane electrode assembly (40); diffusion media in contact with one electrode of membrane electrode assembly; and bipolar plate in contact with diffusion media such that reactant introduced into bipolar plate travels along channels, where the nickel-based alloy used for bipolar plate establishes electrical contact; and    (2) preparation of polymer electrode membrane fuel cell comprising arranging membrane electrode assembly having membrane disposed between anode (20) and cathode (30); arranging anode diffusion layer and cathode diffusion layer; and arranging stainless steel bipolar plate (170), reactants introduced from fuel source and oxygen source which can be delivered to anode and cathode.
