摘要：
LaCo0.6Ni0.4O3-δ(LCN) as cathode contact material (CCM) for application in solid oxide fuel cell (SOFC) is studied in this paper. LCN is prepared through the polymeric steric entrapment precursor route with polyvinyl alcohol (PVA) as the entrapment agent and then calcined at 800 °C and 1100 °C for 3 h respectively. Polished SUS430 pellets heated at 800 °C for 6 days as well as the untreated ones are used as interconnect. The assembly of LCN calcined at 800 °C with pretreated SUS430 at 800 °C for 6 days exhibit the best performance of a low and stable ASR value about 112 mΩ cm2at the end of the 200 h test. The calcination temperature and the pretreatment of interconnect are considered to be crucial factors affecting the ASR property of LCN CCM for application in stack. © (2014) Trans Tech Publications, Switzerland.
