Stromführendes Bauteil für eine Schmelzkarbonatbrennstoffzelle mit Korrosionsschutzbeschichtung

摘要

The invention concerns a current-carrying component for a fused carbonate fuel cell, in particular an anode current collector or bipolar plate, with a special steel substrate (1) and an anticorrosive coating provided thereon. According to the invention, at least one first layer (2) and one second layer (3) are formed on the substrate (1). The first layer (2), which consists of a material which is inert with respect to the anode gas atmosphere and is not wetted by the molten electrolyte, is applied to the component surface, and the second layer (3), which consists of a material which essentially does not mix with the material of the first layer (2), is formed between the first layer (2) and the substrate (1).
