    Abstract

    In this study, we successfully fabricated the perovskite materials for anode-supported proton ceramic fuel cells (PCFCs). This was achieved using an inexpensive commercial thermal inkjet printer, which is an economical and efficient inkjet printing technique. The ceramic ink source was synthesized by dissolving PrBa0.5Sr0·5Co1·5Fe0·5O5+δ (PBSCF) as a cathode nanopowder as a pigment material in ethanol and propylene glycol methyl ether-based solvents with a variety of surfactants. We could optimize 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 conditions. 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 inkjet printing.
