Method for manufacturing by aluminium diffusion a surface layer within a fuel cell component and corresponding oxidation resistant component

摘要

An oxidation resistant fuel cell component and a method for creating an aluminum diffusion surface layer (10) within a fuel cell component to reduce chromium contamination occurring during operation of a fuel cell are disclosed. Generally, an aluminum-containing slurry may be applied to the fuel cell component. The component may then be heated to diffuse aluminum into the component and to form an aluminum diffusion surface layer (10) therein. The surface layer may be characterized by an intermetallic aluminum-containing phase extending below the surface (12) of the fuel cell component.
