A test fixture and methodology was developed for testing anode-supported SOFC button cells downstream from a chromia pellet placed in the cathode air stream at a prescribed temperature to control volatilization of Cr vapor species. A porous alumina foam coated with a Cr gettering material is then placed downstream from the cell to capture Cr from the cathode air stream. The Cr gettering coating is composed of Na₂CO₃, which reacts with Cr vapor species to form Na₂CrO₄. The coating and its reaction product are both water soluble which facilitates dissolving them from the porous substrate for subsequent ICP analysis to determine the concentration of the resulting aqueous solution. The mass of collected Cr can then be calculated and used to determine the average concentration in the known volume of air that flowed past the cathode over the duration of the test. Electrochemical tests of cells with LSM/YSZ cathodes were performed with the chromia pellet at varying conditions of temperature and humidity to elicit various levels of Cr volatility. Multiple cells were tested at each condition for 600 to 1000 hours. Molar concentrations of Cr in the cathode air as small as 4×10^-11 were found to cause ~4%/kh degradation in performance.
