We have fabricated a solid oxide fuel cell (SOFC) using BaCe0.8Y0.2Ox (BCY20) proton conductor as the electrolyte. An {approx} 10-{micro}m-thick dense BCY film was prepared on a porous Ni/BCYcermet (i.e., ceramic/metal composite) substrate by a dip coating process. The gas-permeable Ni/BCY cermet substrate backed with nickel mesh was used as the anode, and a platinum paste backed with platinum mesh served as the cathode. The current-voltage characteristics of the BCY-based SOFC were measured in the temperature range 450-800 C using wet air on the cathode side and hydrogen on the anode side. The power density of the fuel cell was {approx}90 and {approx}1500 mW/cm2 at 450 and 800 C,respectively.
