Abstract
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.
