Abstract
This study reports on the fabrication of the perovskite materials for anod-supported proton ceramic fuel cells (PCFCs) using inkjet-printing (IJP) method. The ceramic ink source was synthesized by dissolving PrBa0.5Sr0.5Co1.5Fe0.5O5+d (PBSCF) as a cathode nanopowder as a pigment material in ethanol and propylene methyl ether based solvents with a variety of surfactants. We could optimized the precise cathode microstructure through grayscale control using commercial software. We achieved high performance in the low-temperature region. Moreover, it was stable even under long-term operation condition. A peak power density of 728 mWcm-2 at 600 C was achieved. This verified that the performance was maintained without significant degradation for 80 h at 500 C. We propose an efficient method for fabricating high-quality and precise PBSCF cathodes in PCFCs using IJP.
