SUB-AREA OF INTEREST 3B: Electrodes - Quantification and Understanding of Cr Poisoning of Cathode Activity. Financial assistance applications are sought for research to elucidate and quantify the effect of Cr-related electrochemical degradation of SOFC material systems with particular emphasis on the cathode/interconnect system. It has been observed that under certain conditions (650 C - 1000 C) exposure to volatile Cr species has been shown to degrade the performance of the SOFC cell. This topic solicits proposals for research to elucidate and quantify the effect of Cr-related electrochemical degradation at the cathode/electrolyte interface. Quantitative exposure response information is sought to enable estimates of long-term cathode performance in Cr-containing environments. The goal is to allow designers of stack configurations to determine the allowable level of Cr in various materials and the level of Cr transport mitigation required. Understanding of the Cr poisoning mechanisms is also sought and may lead to strategies to enable cathodes to become more Cr tolerant.
