Figure 4: Rate and catalyst potential response to step changes in applied current during C2H4 oxidation on Pt deposited on YSZ, an O2- conductor. T = 370 oC, 
pO2= 4.6 kPa, pC2H4= 0.36 kPa. The catalytic rate increase, Δr, is 25 times larger than the rate before the current application, r0, and 74000 times larger than the rate I/2F, of O2- supply to the catalyst. NG is the Pt catalyst surface area, in mol Pt, and TOF is the catalytic turnover frequency (mol O reacting per surface Pt mol per s). Reprinted with permission from Academic Press [3].
