Abstract: A high temperature electrochemical cell component includes a bulk portion and a surface portion including one or more alkaline earth metal-containing, cobalt free and nickel free, oxides reactive with Cr(HO2)2 such that a most stable reaction between each one of the oxides and the Cr(HO2)2 has a reaction energy of about −0.1 to −0.35 eV/at, the oxide(s) being non-reactive with water, the high temperature electrochemical cell having an operating temperature of about 600-1000ºC.

Abstract: A high temperature electrochemical cell includes a solid electrolyte separating a cathode and an anode, an anode flow field adjacent the anode, a cathode flow field, having an exhaust gas stream pathway, downstream from the cathode, and a thermal management system including a controller programmed to, in response to the exhaust gas stream temperature input, activate at least one component, configured to reduce temperature of the exhaust gas stream to a temperature within a threshold range corresponding to a temperature range promoting condensation of Cr-containing gas into solid, liquid, or aqueous Cr2O3 and H2CrO4, the high temperature electrochemical cell having an operating temperature of about 600-1000° C.
