摘要

Proton conducting solid oxide fuel cells (H–SOFCs) with BaZr_0·1Ce_0·7Y_0·2O_3-δ as electrolyte were fabricated to couple the removal of nitrogen oxides in power generation technology. Specially, a deliberately designed cathode with the composition of La_0·3Sr_0·7Mn_0·8Mg_0·2O_3−δ was prepared to realize this dual function. The results indicated that the incorporation of Mg ions in La_0·3Sr_0·7MnO_3−δ can improve its ability to adsorb NO and the cathode activity. At 800 °C, when using the NO as oxidant, single cell with La_0·3Sr_0·7Mn_0·8Mg_0·2O_3−δ cathode was able to obtain peak power density of 48 mW cm⁻² and achieve the conversion of NO to N₂ more than 48%. These findings suggested that power generation coupling deNO via H–SOFC is possible and La_0·3Sr_0·7Mn_0·8Mg_0·2O_3−δ was a promising cathode for this application.
