Diffusion and Gas Conversion Analysis of Solid Oxide Fuel Cells at Loads via AC Impedance
Figure 1
Nyquist plot for a button cell anode operating at 800°C and 175 mA cm−2 and fed with 3% H2O and H2 diluted with varying amounts of N2. Data fits were obtained with the anode equivalent circuit model in the right-hand corner of the figure.
