Preparation and Characterization of NiO-LSCM/LSCM Dual Composite Anode for IT-SOFC

Abstract

The LSCM (La0.7Sr0.3Cr0.5Mn0.5O3-δ) powders were synthesized by glycine-nitrate process (GNP). An anode functional layer (AFL) LSCM was fabricated on an porous NiO-LSCM anode substrate by slurry spin coating. The effect of pore-former, sintering temperature and sintering time on the quality of thin film was investigated. The film with good apparent morphology was obtained when the operating parameters were fixed as follows: the pore-former is ethyl cellulose, the content of ethyl cellulose is 5 wt.%, the sintering temperature is 1000 °C and the sintering time is 4 h.

“…19 In addition, Ni adhesion to the surface of the LSCM substrate helps improve the conductivity and catalytic activity of the anode support. 20 However, Ni-based catalysts are susceptible to carbon deposits and deactivate during long-term use, and have high tendencies to sinter, which may deteriorate their battery performance. 21 The use of different metal-based catalysts, such as alloys of nickel and copper or cobalt, can improve the catalytic stability and coke resistance by optimizing the catalytic activity of SOFC anodes.…”

“…It is reported that strontium and strontium chromate La 0.75 Sr 0.25 Cr 0.5 Mn 0.5 O 3− δ (LSCM) are promising substitute anode materials 17,18 for Ni–YSZ cermet, and they exhibit stable performance as a catalytic material for H 2 and CH 4 redox when a low steam to hydrocarbon ratio is used 19 .
