Synthesis and Processing of Perovskite Oxides for Solid Oxide Fuel Cells Anode Fabrication

Abstract:

In the present work materials alternative to Ni/YSZ cermets anodes for Solid Oxide Fuel Cells (SOFCs) have been studied in order to overcome the problems related to catalytic deposition of carbon and the limited tolerance to sulphur. Anodes consisting of (La0.75Sr0.25)(Cr0.5Mn0.5)O3-δ (LSCM25) have been investigated with regard to synthesis and processing related problems. Single phase LSCM25 perovskites were synthesized by urea/nitrates gel combustion method and the as prepared powders were used to produce green tapes by tape casting processing. Thick LSCM25 substrates, suitable as anodes in anode supported SOFC fabrication, were successfully obtained by sintering of green LSCM25 laminates.
