摘要：
In order to improve the performance of molten carbonates fuel cells, we have investigated the catalytic activity of LaNiO3 and NiO for the oxygen reduction reaction (ORR) on a meniscus electrode in Li/Na eutectic carbonates with La oxide. The apparent current density (i(0)) of LaNiO3 was slightly smaller than that of NiO. The partial pressure of CO2 (p(CO2)) and O-2 (p(O2)) dependences of ORR were obtained on LaNiO3 and NiO, and the reaction mechanism of ORR on LaNiO3 was almost same to that on NiO at 923 K.
