Abstract (en)
[origin: WO2020200353A1] The invention relates to a layer system (1) for coating a bipolar plate (2), comprising at least one cover layer (1a) made of tin oxide, wherein at least one metal oxide of the group comprising tantatalum oxide, niobium oxide, titanium oxide, zirconium oxide, and hafnium oxide is homogenously dissolved in the tin oxide, and the electric conductivity of the cover layer (1a) is greater than or equal to 102 S/cm. The invention additionally relates to a bipolar plate (2, 2') with an anode side and a cathode side, comprising a substrate (2a, 2a') and such a layer system (1), and to a fuel cell (10) or an electrolyzer comprising such a bipolar plate (2, 2').
