摘要: Abstract A perovskite-type oxide LaNi 0.8 Co 0.2 O 3 is prepared as a direct borohydride fuel cell (DBFC) cathode catalyst. Its electrochemical properties are studied by cyclic voltammetry. The results demonstrate that exhibits excellent activity with respect to the oxygen reduction reaction (ORR) and good tolerance of BH 4 − ions. Maximum power densities 114.5 mW cm −2 at 30 °C 151.3 mW cm 62 °C obtained, stability (300-h stable performance 20 mA cm ) also exhibited, which shows such oxides can be catalysts for DBFCs.
