Significantly different cell power outputs are measured. The total power output of the Cell-2.25 is 1.35 similar to 1.68 times to that of the Cell-1.0. The discrepancy is considered to originate from two major reasons: 1. limited lateral conduction and 2. thin thickness of the cathode. The cell performance can be overestimated when the smaller area is chosen, or underestimated when the larger area is chosen as the active area between the current collection area and the cathode area. The present study identifies another important factor to be considered to exactly assess the performance of the SOFC implementing thin-film-processed electrode.
