Syngas reactivity over (LaAg)(CoFe)O3 and Ag-added (LaSr)(CoFe)O3 anodes of solid oxide fuel cells

▶ The reactivity with hydrogen as the anode fuel is larger than that with CO. ▶ The reactivity increases with increasing hydrogen content in the syngas. ▶ Ag-added (LaSr)(CoFe)O3 has higher syngas reactivity than (LaAg)(CoFe)O3. ▶ Ag-added (LaSr)(CoFe)O3 has better stability in hydrogen than (LaAg)(CoFe)O3.
