Zusammenfassung:A fuel cell assembly includes a fuel cell stack including a plurality of fuel cells, an incoming oxidizing gas flow path configured to deliver an oxidizing gas to the plurality of fuel cells, and a chromium-getter material located in the incoming oxidizing flow path. A fuel cell includes an electrolyte, a cathode electrode on a first side of the electrolyte, an anode electrode on a second side of the electrolyte, and a chromium-getter material on the cathode electrode.
