Prior to e-ODH testing, 80 sccm of pure Ar was passed through the inside of the alumina tube, while 200 sccm of atmospheric air was purged on the cathode surface and analyzed with the GC for the presence of O2 and N2 to detect leaks in the cell assembly. The anode surface was purged with 10%H2-90%Ar for catalyst reduction. To initiate e-ODH testing, 80 sccm of 96% C2H6-4% N2 was passed on the anode side and the open cell voltage (OCV) was evaluated for stability. After stabilization, current in the range of 0 -1 A/cm 2 was applied and the outlet gas composition was measured using the GC.
