Abstract
Planar single cells using zirconia plates (46-mm diameter and 500-μm thickness) were fabricated by the tape casting method. The open-circuit voltage was 1.07 V and the maximum power output was 0.22 W/cm2 with hydrogen and air as fuel and oxidant, respectively. Cathodic polarization decreased drastically during cell operation. Anodic polarization increased more than the internal resistance of the zirconia plate with lowering temperature. In the case of direct introduction of methane, the cracking reaction of methane and subsequent direct electrochemical oxidation of carbon seemed to proceed preferentially on the anode.
