For both micro- and nanoporous electrodes, a consistent relationship was found between the reaction field and the particle size, with the reaction field being about three times the particle size under our conditions. The surface reaction resistance and the effective oxygen transport resistance of microporous and nanoporous electrodes show overall similar values, with differences on the order of 0.5–1 orders of magnitude, indicating that they are largely comparable. In the DC polarization measurements, the current density of the microporous sample, when multiplied by a constant factor, closely matched that of the nanoporous sample. This suggests that the reaction mechanisms at both these electrodes were similar. This study demonstrates that the improvement in electrode performance with reduced particle size does not arise from intrinsic changes in the material properties, but rather from the increase in specific surface area.
