Abstract

Recent research into the upscaling and implementation of Rh/Ce_0.80Gd_0.20O_1.90 co-impregnated La_0.20Sr_0.25Ca_0.45TiO₃ (LSCT_A-) anodes in electrolyte-supported SOFC at short-stack industrial scales has resulted in extremely robust performance under realistic operation and tolerance to harsh conditions. Furthermore, evaluation of the mechanical strength of LSCT_A- and incorporation of this material into anode-supported SOFC also yielded promising performance at the button cell scale (using Ni and CeO₂ catalyst impregnates). The knowledge on ceramic processing obtained during these previous research campaigns may be used to develop anode-supported SOFC with LSCT_A- 'backbones' that have been optimised for high mechanical strength, high 'effective' electronic conductivity and sufficient porosity. Therefore, this manuscript details the preparation of anode-supported SOFC using the thick-film ceramic processing technique of aqueous tape casting, the optimisation of anode microstructure through addition of aqueous solvent-compatible graphitic and methacrylate polymer pore formers and the co-sintering of a LSCT_A- support with a typical SOFC electrolyte material.
