For highly dense and thin electrolyte film growth, anode functional layer and anode interlayer are deposited on porous anode support by electrostatic slurry spray deposition and PLD, respectively. As a result, high open circuit voltage of 0.98 V is obtained after anode reduction at 600°C, indicating that the fabricated BZY electrolyte effectively blocks gas permeation. Electrochemical performance of the PCFC is obtained with peak power densities of 55-171 mW/cm2 at an operating temperature regime of 450-600°C. ？ The Electrochemical Society.
