摘要：

LaNi(Fe)O-3 (LNF) is one of the promising cathode materials for intermediate- temperature solid oxide fuel cells (SOFCs). However, LNF is more reactive with ZrO2-based electrolyte than conventional La(Sr)MnO3 in the sintering temperature region. In this paper, we examine the relationships among LNF sintering characteristics, reactivity, and cell performance to investigate the potential of LNF. We show that the current-voltage characteristics of cells using LNF as the cathode are drastically improved by preliminary loading at a very high current density. The cathodic overvoltage became one order of magnitude smaller after the preliminary loading, and the cells generated the maximum power density of 1.56 W/cm(2) at 800 degreesC.
