Electrochemical cell exhaust management system

An electrochemical cell chrome-getter material comprising:

• at least one metal oxide with an alkaline earth metal present in an electrochemical cell exhaust system, the oxide being reactive with Cr(HO2)2 and an aluminum-based metal surface and being non-reactive with water such that the material is structured to react with the Cr(HO2)2 to capture the chromium and form a liquid, aqueous, or solid Cr-containing compound, the chrome-getter material excluding SrCoO3 and SrNiO3.

A solid oxide fuel cell comprising:

• a solid electrolyte separating a cathode and an anode,
• an anode flow field downstream from the anode, and
• a cathode flow field downstream from the cathode and including at least one component having a bulk portion forming a base to a surface portion including one or more cobalt-free and nickel-free alkaline earth metal-containing Cr-getter oxides reactive with Cr(HO2)2, the oxides being non-reactive with water.
