    摘要: Fuel cell bipolar plates are made by depositing a pinhole free corrosion resistant and/or a conductive layer on a metal plate using an atomic layer deposition method. In one embodiment, a conductive layer is deposited on an anodized metal plate using atomic layer deposition method. In another embodiment, at least one corrosion resistant metal oxide layer and at least one conductive layer are deposited on a metal plate individually using atomic layer deposition method. In yet another embodiment, a corrosion resistant and conductive metal oxynitride layer is deposited on a metal plate using an atomic layer deposition method.

    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.
