Performance of Anode Microstructure Controlled Ni-ScSZ/LSGM/LSCF-Ag SOFCs by Low Temperature Fabrication Process

Abstract

An anode microstructure controlled solid oxide fuel cell was successfully fabricated by low temperature process and the maximum power density of the cell was 33mW/cm2 at 600 degree C. The LSGM electrolyte thin film was available by post-annealing at 1000 degree C after deposition using radio frequency magnetron sputtering. Thus, the sintering temperature of the anode support could be reduced. The porosity and the diameter of Ni and ScSZ particles were 55% and 0.23 μm and 0.14 μm when the anode support was fabricated by sintering at 1100 degree C and adding 10 wt. % of the pore former. The wider area of three phase boundary is obtained by the low temperature process.
