Brennstoffzellenstapel und Verfahren zum Herstellen eines Brennstoffzellenstapels

摘要

In order to provide a component of a fuel cell unit that has an electric insulation effect at the operating temperature of the fuel cell unit and that has an adequate electrically insulating effect and an adequate mechanical strength also at a high operating temperature of the fuel cell unit, it is proposed that the component comprises a basic body and at least one electrically insulating insulation layer, which is disposed on the basic body and contains aluminium oxide, wherein the insulation layer is produced by anodizing an aluminium-containing layer disposed on the basic body.
