Potential variations in cells with different 3PBs/2PBs ratios under the stoichiometric conditions for partial oxidation as a function of time.
The cells had different 3PBs/2PBs ratios and the thickness of the Ni-YSZ composite remained constant. The 3PBs/2PBs ratio of each cell was determined by c-AFM surface analysis and the corresponding surface images are shown in the inset. (a) The anode that had the highest 3PBs/2PBs ratio (1.08 m−1) exhibited stable OCV. (b) The anode that had an intermediate 3PBs/2PBs ratio (0.99 m−1) exhibited oscillation of the OCV. (c) The anode that had the lowest 3PBs/2PBs ratio (0.78 m−1) did not exhibit a stable OCV.
