Abstract: Layered perovskite oxide LaSr3Fe3O10 (LSFO) was characterized by electrochemical measurements and XRD. The H2 sensing property of the oxide with 15wt% Pd/LSFO anode catalyst in H2 at room temperature was examined. As for H2 sensing, the potential about 0.9 V was gained in the presence of H2 without cathode catalyst. Furthermore, the membrane potential for concentration cell of NaOH with LSFO showed negative value, and the potential with anion exchange membrane (AEM) also showed negative value. These results suggest that LSFO shows OH- conductivity and the possibility of a new type fuel cell by using LSFO as electrolyte.
