Abstract

The present invention relates to a method of coating one or more metal components of a fuel cell stack, such as a bipolar plate, an electrode, gaskets etc., the method comprising the steps of providing an uncoated metal component; etching said uncoated metal component; optionally depositing an adhesion layer on the etched uncoated metal component; and depositing a carbon coating on either the adhesion layer or on the etched uncoated metal component, with the adhesion layer and the carbon coating respectively being deposited by means of one of a physical vapor deposition process, an arc ion plating process, a sputtering process, and a Hipims process. The invention further relates to a component of a fuel cell stack and to an apparatus for coating one or more components of a fuel cell stack.
