    摘要： A bipolar plate to reduce electrical contact resistance between the plate and a diffusion layer used in a fuel cell. The opposing surfaces of the plate define flow channels with upstanding lands interspersed between them. The lands of the plate form an electrically-conductive contact with a diffusion layer in the fuel cell. At least a portion of the electrically-conductive contact is made up of a nickel-based alloy that reduces the contact resistance between the plate and the diffusion layer as a way to achieve improved electric current density. In one form, the alloy can be used as the primary material in the plate, while in another, it can be used as a coating deposited onto a conventional stainless steel plate.

    摘要： A fuel cell includes a first valve metal flow field plate. The first valve metal flow field plate has a first cooling channel adapted to receive an aqueous coolant and to contact the aqueous coolant at a position that inhibits the formation of shunt currents when the fuel cell is incorporated in a fuel cell stack. A field assembly includes a first metal flow field plate having a first cooling channel adapted to receive an aqueous coolant is also provided. A valve metal plate is disposed over the first metal flow field plate in the flow field assembly. Fuel cell stacks using the valve metal-containing flow field plates are also provided.
