Electrochemical measurements of fuel cells based on proton conductor electrolyte Ba₂(In_0.8Ti_0.2)₂O_5.2−n(OH)_2n and prepared through a tape casting process and a co-pressing of anode-composite powder and electrolyte tape were performed at 500 °C under wet H₂. The varying parameter between the prepared cells was the thickness of the electrolyte that can be controlled during the tape casting process. The maximum power density was obtained for the cell with the thinnest electrolyte (35 μm) and was about 22 mW cm⁻² with an ohmic resistance about 2 Ω cm² at 500 °C.
