In some embodiments, a solid oxide fuel system is provided. The solid oxide fuel cell system may include a chromium-getter material. The chromium-getter material may react with chromium to remove chromium species from chromium vapor. The solid oxide fuel cell system may also include an inert substrate. The chromium-getter material may be coated onto the inert substrate. The coated substrate may remove chromium species from chromium vapor before the chromium species can react with a cathode in the solid oxide fuel cell system.
