NH{sub 3} Cd, Hg, and Sn have no noticeable effects on carbonate fuel cell performance. Zn and Pb (the latter in the presence of Se) had minor effects, while the interactions of H{sub 2}S, HC{ell}, H{sub 2}Se and As are more significant. Because H{sub 2}S had already been extensively investigated earlier by various groups, the focus in this study was centered on the latter three elements. It appears that HC{ell}, H{sub 2}Se, and As need to be limited to sub-ppM levels in a manner similar to H{sub 2}S. These findings, of course, should be considered qualitative because they were obtained in single, isothermally operated, bench-sale cells, and are applicable for individual contaminants.
