Abstract (en)
[origin: US2009155667A1] In order to provide a bipolar plate for a fuel cell unit, wherein the bipolar plate comprises a support layer and a protective layer, wherein the protective layer comprises an at least binary oxide system with at least two different types of metal cations, the protective layer of which reliably reduces chromium evaporation even in long-term operation and which also meets the other requirements set for a bipolar plate, it is proposed that one type of metal cation of the oxide system of the protective layer is Fe.
