Mass current density (jmass) for Pt/C catalysts reported in the literature versus the corresponding η value, both of which were measured at 10 mA/cmgeom2. Additional information about the Pt/C catalysts and the literature references are given in Table S1. (a) The data follow an exponential-type relationship, which is confirmed by (b), which shows essentially the same as (a) but as a plot of η versus the log 10 of jmass of the Pt/C catalysts.
